São Tomé e Príncipe: AI regulation & deadlines

No AI-specific statute is in force, but São Tomé e Príncipe carries a Portuguese Lei 67/98-lineage automated-decision prohibition that is stricter on the way out than Angola's and more generous on disclosure. Art. 13.º of Lei n.º 3/2016 — Lei de Protecção de Dados Pessoais gives any person the right not to be subject to a decision producing effects in their legal sphere or significantly affecting them, taken exclusively on automated processing intended to evaluate aspects of their personality — professional capacity, credit, trustworthiness or conduct. The only exceptions are the two of the parent law: a decision in the conclusion or performance of a contract, conditioned on the person's request having been satisfied or on adequate measures guaranteeing their legitimate interests including the right of representation and expression; and a decision authorised by a law laying down safeguards. Unlike Angola, nothing lets the supervisory authority licence a prohibited decision case by case. Art. 11(1)(c) adds a right to obtain knowledge of the reasons underlying the automated processing of one's data — razões rather than the parent law's lógica — exercisable on request; the art. 10 information duty carries no automated-decision item. Scope under art. 3 is the familiar four-limb reach including a means-in-territory limb that obliges a foreign controller hosting on São Tomé infrastructure to appoint a local representative. Enforcement bites directly: art. 32(1) lists art. 13 among the provisions whose breach is an administrative infraction of 25,000,000 to 50,000,000 dobras as written in the 2016 text, applied by the Agência Nacional de Protecção de Dados Pessoais under art. 35, with accessory prohibition of the processing and publicity of the conviction under arts. 42-43 and a qualified-disobedience crime under art. 39 for ignoring an order to stop. Approved 15 February 2016, promulgated 18 March 2016 and published in the Diário da República n.º 39 of 10 May 2016; art. 47 defers entry into force to the general rule rather than fixing a date. 1 obligation tracked — 1 in force.

São Tomé e Príncipe Binding

Lei 3/2016 art. 13.º — the Lusophone prohibition without Angola's regulator escape hatch, and with a right to the reasons

Binds Responsáveis pelo tratamento — controllers — with subcontratantes (processors) bound through art. 17, which forbids anyone acting under the authority of the controller or processor, and the processor itself, from processing personal data without the controller's instructions save under legal obligation. Art. 3(1) applies the Law to processing by wholly or partly automated means and to non-automated processing of personal data contained in or intended for manual files. Art. 3(2) sets four territorial limbs: processing by a controller headquartered in São Tomé e Príncipe; processing in the context of the activities of a controller established in São Tomé e Príncipe even where that controller is not headquartered in national territory; processing outside national territory in a place where São Tomé law applies by force of public or private international law; and processing by a controller not established in São Tomé e Príncipe that resorts, for the processing, to means situated in national territory. Art. 3(3) makes that last limb wide in the same terms Angola uses — a controller is deemed to resort to means in São Tomé territory where the processing operations are carried out with means situated in national territory or where the personal data are hosted on means so situated, the mere use of such means for the collection, recording or transit of personal data in national territory being enough — and art. 3(4) then obliges that controller to designate a representative established in São Tomé e Príncipe. A foreign scoring, credit or hiring-assessment operator that merely hosts on São Tomé infrastructure is therefore inside art. 13 and owes a local representative. Impact tier: all entities — art. 13 carries no employee-count, turnover, sector or high-risk-system threshold, and its named evaluation grounds (professional capacity, credit, trustworthiness, conduct) put hiring and credit-scoring deployers squarely in scope.. Article 13.º of Lei n.º 3/2016 — Lei de Protecção de Dados Pessoais is São Tomé e Príncipe's automated-decision provision, and it is the second Lusophone row on the tracker after Angola. Both descend from Portugal's Lei 67/98 and the operative sentence is close to word-for-word: under art. 13(1), «qualquer pessoa tem o direito de não ficar sujeita a uma decisão que produza efeitos na sua esfera jurídica ou que a afecte de modo significativo, tomada exclusivamente com base num tratamento automatizado de dados destinado a avaliar determinados aspectos da sua personalidade, designadamente a sua capacidade profissional, o seu crédito, a confiança de que é merecedora ou o seu comportamento» — any person has the right not to be subject to a decision producing effects in their legal sphere or significantly affecting them, taken exclusively on the basis of automated processing intended to evaluate certain aspects of their personality, namely their professional capacity, their credit, their trustworthiness or their conduct. Where the two Lusophone rows part company is on the way out and on what the data subject gets to see. São Tomé keeps only the two statutory exceptions of the parent law — art. 13(2)(a), a decision taken in the conclusion or performance of a contract, conditioned on the person's own request having been satisfied or on adequate measures guaranteeing their legitimate interests, expressly their right of representation and expression; and art. 13(2)(b), a decision authorised by a law that lays down measures guaranteeing the data subject's rights and legitimate interests. There is no third route: nothing lets the Agência Nacional de Protecção de Dados Pessoais licence an otherwise-prohibited decision, which is exactly the limb Angola added as art. 29(3) and the reason Angola stands alone on the tracker. In the other direction São Tomé is the more generous of the pair, because art. 11(1)(c) gives the data subject the right to obtain from the controller «o conhecimento das razões subjacentes ao tratamento automatizado dos dados que lhe digam respeito» — knowledge of the reasons underlying the automated processing of data concerning them. The parent Portuguese provision speaks of the lógica subjacente, the underlying logic; São Tomé's drafters wrote razões, reasons, which on its face asks for the grounds of the processing rather than the mechanics of the model, and it is drafted as an access right exercisable on request rather than as a notice duty — the art. 10 information list carries no automated-decision item at all. Angola's Lei 22/11 has no equivalent of either. So among the three African rows added this month the shape is: São Tomé prohibits the decision and lets the data subject ask why the machine processed them, Angola prohibits the decision and never lets them ask, and the Democratic Republic of the Congo never prohibits it but compels disclosure of the underlying logic three times over. Impact tier: all entities.

Force. The Law was approved by the Assembleia Nacional in São Tomé on 15 February 2016, promulgated by President Manuel do Espírito Santo Pinto da Costa on 18 March 2016, and published in the Diário da República n.º 39 de 10 de Maio de 2016 at pp. 285-299 — the gazette number and date run in the running head of every page of the text read. The date carried here is that publication date, and it is the one point in the entry that is not exact to the day: art. 47.º (Entrada em vigor) says only «a presente lei entra em vigor nos termos legais», deferring to the general rule on the entry into force of diplomas rather than fixing a date or a vacatio period on its face, so the operative date is the publication date or a small number of days after it. Applying Deadline Specificity strictly, that residual is stated rather than papered over: no primary text of the São Tomé rule on entry into force of diplomas was located in this pass, secondary accounts point to the five-day PALOP vacatio inherited from Base LXXIX of Lei 5/72, and that account has not been verified against primary text and is not relied on here. Ten years on, nothing on the tracker turns on the difference. Art. 45 sets the only transition and it does not touch art. 13: processing existing in manual files at entry into force was given two years for conformity with arts. 7, 8, 10 and 11. Supersession: none — no successor or amending law was found, and no AI-specific statute is in force in São Tomé e Príncipe. Text read in full in the copy of the Diário da República pages published by the Red Iberoamericana de Protección de Datos, the network of Ibero-American data-protection authorities of which the São Tomé Agência Nacional de Protecção de Dados Pessoais is a member; the file is the gazette typesetting itself, carrying the DR running heads, page numbers 285-299 and the closing signature block, not a re-keyed edition. Coverage of the read: arts. 2 principles, 3 scope and 4 definitions; the whole of Capítulo III on data-subject rights, arts. 10 information, 11 access, 12 opposition, 13 automated individual decisions and 14 compensation, verbatim; arts. 16-18 on sensitive-data authorisations, processors and professional secrecy; the whole enforcement chain — arts. 30-35 administrative infractions and their fines, arts. 36-41 the criminal section, arts. 42-43 accessory penalties; art. 44 on the Agência; and arts. 45-47 the transitional and final provisions. Confidence high on the substance: art. 13 and art. 11(1)(c) were read verbatim in the gazette text and the fine attaching to art. 13 was traced to the enumerated list in art. 32(1) rather than assumed. The Agência Nacional de Protecção de Dados Pessoais, whose organic law art. 44 leaves to the Assembleia Nacional, does exist and is operational — it is a listed member of the African Network of Data Protection Authorities and of the Rede Lusófona de Protecção de Dados, where it leads the video-surveillance working group — so unlike Equatorial Guinea's never-created Órgano Rector, the enforcement route in art. 35 has an addressee.

Stated maximum penalty — 25,000,000 to 50,000,000 dobras, and the notable point is that the fine reaches art. 13 directly. Art. 32(1) enumerates by article number the provisions whose breach is an administrative infraction at that band — arts. 5, 10, 11, 12, 13, 16, 17 and 25(3) — so both the automated-decision prohibition in art. 13 and the right to know the reasons underlying automated processing in art. 11 are inside the sanctioned list. That is the opposite of Angola, where art. 29 appears in neither art. 51 contravention list and enforcement has to run through a complaint, a judicial reparation claim or the crime of qualified disobedience. Art. 32(2) sets a higher band, 45,000,000 to 90,000,000 dobras, for breach of arts. 6, 7, 8, 9, 19 and 20. Art. 31 sets the notification-failure band — 50,000,000 to 120,000,000 dobras for a natural person, 100,000,000 to 200,000,000 for a group without legal personality, and 250,000,000 to 500,000,000 for a legal person — doubled under art. 31(2) where the data are subject to prior control, and art. 34(1) makes negligence always punishable there. All amounts are as written in the 2016 text and are nominal dobras of that date; São Tomé e Príncipe redenominated its currency after the Law was passed, so the figures need conversion before they are quoted as a present-day exposure, and no conversion is asserted here because none was verified against primary text in this pass. Art. 35 gives the application of the fines to the Agência Nacional de Protecção de Dados Pessoais and makes its decision an enforceable title where it is not challenged in the legal period. Alongside the fines, art. 42 allows accessory penalties — temporary or definitive prohibition of the processing, blocking, erasure or total or partial destruction of the data, publicity of the conviction under art. 43 at the convicted party's expense in a widely circulated Portuguese-language periodical for not less than 30 days, and public warning or censure of the controller by the Agência. The criminal section sits behind that: art. 36 punishes intentional failure to notify or to seek authorisation, false information in a notification, diversion or use of personal data incompatibly with the purpose determining their collection, and unlawful interconnection, with up to one year's imprisonment or a fine up to 120 days; art. 37 punishes undue access and art. 38 the vitiation or destruction of data with up to two years; art. 39 makes it qualified disobedience to fail, after notification, to interrupt, cease or block processing, or to refuse the Agência the cooperation demanded of one; art. 40 punishes breach of professional secrecy with up to two years, aggravated by half where the agent is a public official or acted for gain; and art. 41 makes attempt always punishable. Under art. 33(1), where the same act is both a crime and an administrative infraction, the agent is always punished as for the crime.

Questions & answers

From the data

When does Lei 3/2016 art. 13.º take effect in São Tomé e Príncipe?

Lei 3/2016 art. 13.º is already in force, with obligations live since May 10, 2016. No AI-specific statute is in force, but São Tomé e Príncipe carries a Portuguese Lei 67/98-lineage automated-decision prohibition that is stricter on the way out than Angola's and more generous on disclosure. Art. 13.º of Lei n.º 3/2016 — Lei de Protecção de Dados Pessoais gives any person the right not to be subject to a decision producing effects in their legal sphere or significantly affecting them, taken exclusively on automated processing intended to evaluate aspects of their personality — professional capacity, credit, trustworthiness or conduct. The only exceptions are the two of the parent law: a decision in the conclusion or performance of a contract, conditioned on the person's request having been satisfied or on adequate measures guaranteeing their legitimate interests including the right of representation and expression; and a decision authorised by a law laying down safeguards. Unlike Angola, nothing lets the supervisory authority licence a prohibited decision case by case. Art. 11(1)(c) adds a right to obtain knowledge of the reasons underlying the automated processing of one's data — razões rather than the parent law's lógica — exercisable on request; the art. 10 information duty carries no automated-decision item. Scope under art. 3 is the familiar four-limb reach including a means-in-territory limb that obliges a foreign controller hosting on São Tomé infrastructure to appoint a local representative. Enforcement bites directly: art. 32(1) lists art. 13 among the provisions whose breach is an administrative infraction of 25,000,000 to 50,000,000 dobras as written in the 2016 text, applied by the Agência Nacional de Protecção de Dados Pessoais under art. 35, with accessory prohibition of the processing and publicity of the conviction under arts. 42-43 and a qualified-disobedience crime under art. 39 for ignoring an order to stop. Approved 15 February 2016, promulgated 18 March 2016 and published in the Diário da República n.º 39 of 10 May 2016; art. 47 defers entry into force to the general rule rather than fixing a date.

Who must comply with AI rules in São Tomé e Príncipe?

Current obligations bind, among others, Responsáveis pelo tratamento — controllers — with subcontratantes (processors) bound through art. 17, which forbids anyone acting under the authority of the controller or processor, and the processor itself, from processing personal data without the controller's instructions save under legal obligation. Art. 3(1) applies the Law to processing by wholly or partly automated means and to non-automated processing of personal data contained in or intended for manual files. Art. 3(2) sets four territorial limbs: processing by a controller headquartered in São Tomé e Príncipe; processing in the context of the activities of a controller established in São Tomé e Príncipe even where that controller is not headquartered in national territory; processing outside national territory in a place where São Tomé law applies by force of public or private international law; and processing by a controller not established in São Tomé e Príncipe that resorts, for the processing, to means situated in national territory. Art. 3(3) makes that last limb wide in the same terms Angola uses — a controller is deemed to resort to means in São Tomé territory where the processing operations are carried out with means situated in national territory or where the personal data are hosted on means so situated, the mere use of such means for the collection, recording or transit of personal data in national territory being enough — and art. 3(4) then obliges that controller to designate a representative established in São Tomé e Príncipe. A foreign scoring, credit or hiring-assessment operator that merely hosts on São Tomé infrastructure is therefore inside art. 13 and owes a local representative. Impact tier: all entities — art. 13 carries no employee-count, turnover, sector or high-risk-system threshold, and its named evaluation grounds (professional capacity, credit, trustworthiness, conduct) put hiring and credit-scoring deployers squarely in scope.. Scope and thresholds vary per instrument — see each row's source for the legal text.

What are the penalties for AI non-compliance in São Tomé e Príncipe?

Stated statutory maxima include: Lei 3/2016 art. 13.º — 25,000,000 to 50,000,000 dobras, and the notable point is that the fine reaches art. 13 directly. Art. 32(1) enumerates by article number the provisions whose breach is an administrative infraction at that band — arts. 5, 10, 11, 12, 13, 16, 17 and 25(3) — so both the automated-decision prohibition in art. 13 and the right to know the reasons underlying automated processing in art. 11 are inside the sanctioned list. That is the opposite of Angola, where art. 29 appears in neither art. 51 contravention list and enforcement has to run through a complaint, a judicial reparation claim or the crime of qualified disobedience. Art. 32(2) sets a higher band, 45,000,000 to 90,000,000 dobras, for breach of arts. 6, 7, 8, 9, 19 and 20. Art. 31 sets the notification-failure band — 50,000,000 to 120,000,000 dobras for a natural person, 100,000,000 to 200,000,000 for a group without legal personality, and 250,000,000 to 500,000,000 for a legal person — doubled under art. 31(2) where the data are subject to prior control, and art. 34(1) makes negligence always punishable there. All amounts are as written in the 2016 text and are nominal dobras of that date; São Tomé e Príncipe redenominated its currency after the Law was passed, so the figures need conversion before they are quoted as a present-day exposure, and no conversion is asserted here because none was verified against primary text in this pass. Art. 35 gives the application of the fines to the Agência Nacional de Protecção de Dados Pessoais and makes its decision an enforceable title where it is not challenged in the legal period. Alongside the fines, art. 42 allows accessory penalties — temporary or definitive prohibition of the processing, blocking, erasure or total or partial destruction of the data, publicity of the conviction under art. 43 at the convicted party's expense in a widely circulated Portuguese-language periodical for not less than 30 days, and public warning or censure of the controller by the Agência. The criminal section sits behind that: art. 36 punishes intentional failure to notify or to seek authorisation, false information in a notification, diversion or use of personal data incompatibly with the purpose determining their collection, and unlawful interconnection, with up to one year's imprisonment or a fine up to 120 days; art. 37 punishes undue access and art. 38 the vitiation or destruction of data with up to two years; art. 39 makes it qualified disobedience to fail, after notification, to interrupt, cease or block processing, or to refuse the Agência the cooperation demanded of one; art. 40 punishes breach of professional secrecy with up to two years, aggravated by half where the agent is a public official or acted for gain; and art. 41 makes attempt always punishable. Under art. 33(1), where the same act is both a crime and an administrative infraction, the agent is always punished as for the crime.. These are the maximum amounts in the instruments; actual enforcement is at the regulator's discretion.
