Portugal — Decreto-Lei n.º 83/2018 (web accessibility)

Portugal's transposition of the EU Web Accessibility Directive (2016/2102): accessibility requirements for public-sector websites and mobile applications, the mandatory declaração de acessibilidade, and AMA, I.P. (Agência para a Modernização Administrativa) as the monitoring authority.

Statute text is Portuguese (the authentic language); this README is curation.

Applicability to EdTech

• Schools are named, not merely implied. The decree-law's own artigo 15.º rewrites artigo 2.º of Lei n.º 36/2011 so that the accessibility duties reach "instituições de ensino superior, estabelecimentos de educação pré-escolar e de educação escolar, públicos e privados com financiamento público" — private schools included, where they carry public funding. That is the widest subject scope of any transposition in the corpus.
• "Funções administrativas essenciais" is defined in schooling terms (artigo 4.º, alínea f)): enrolment, curricular organisation, the school-year calendar, course and class lists. A product doing any of those for a Portuguese school is inside the definition rather than adjacent to it.
• A vendor is reached through procurement, not directly — the duty binds the organismo público. The declaração de acessibilidade is the artefact a buyer will ask a supplier to support: a conformance statement in the AMA model, with a feedback mechanism and a route to complain.
• The compliance dates are all past (artigo 19.º): sites published from 23 September 2018 were due on 23 September 2019, older sites on 23 September 2020, and all mobile applications on 23 June 2021.
• Conformance is presumed from the harmonised standard (artigo 7.º), and in its absence from a named, frozen one: artigo 7.º n.º 2 writes EN 301 549 V1.1.2 (2015-04) into the decree-law by version. The standard has moved on (V3.2.1 and later) and the statute has not, so the text says less than current practice asks for — read the presumption as a floor, not as the specification a buyer will hold you to.
• Disproportionate burden is available but has to be argued (artigo 6.º), and the reasoning belongs in the accessibility statement.

Private-sector ICT accessibility arrives separately, via the European Accessibility Act transposition (DL 82/2022, not yet curated) — which DRE records as applying this decree-law.

Unamended. DRE's own Análise Jurídica records three modifications produced by this act (to the Regulamento Nacional de Interoperabilidade Digital, to artigo 2.º of Lei 36/2011, and the revocation of RCM 155/2007) and none suffered, which is why the original publication is the operative text and DRE offers no Versão Consolidada. The builder's verify re-reads that page and fails the moment an amendment lands.

Oversight

Agência para a Modernização Administrativa, I. P. (AMA) — acessibilidade.gov.pt, the monitoring and reporting body designated by artigo 11.º.

Licence

The corpus reproduces Decreto-Lei n.º 83/2018 from the Diário da República portal, the official gazette.

Portuguese copyright law gives no protection to the texts of laws gathered in compilations. Artigo 3.º, n.º 1, alínea c), of the Código do Direito de Autor e dos Direitos Conexos (PGDL — CDADC, read 2026-10-01) names "As compilações sistemáticas ou anotadas de textos de convenções, de leis, de regulamentos e de relatórios ou de decisões administrativas, judiciais ou de quaisquer órgãos ou autoridades do Estado ou da Administração", and artigo 8.º, n.º 1, provides: "Os textos compilados ou anotados a que se refere a alínea c) do n.º 1 do artigo 3.º, bem como as suas traduções oficiais, não beneficiam de protecção." The code has no separate article that names statutes as such; artigo 8.º is the provision that excludes their texts.

Conditions: none attach to the statute text, because no copyright subsists in it. The corpus still identifies its source: each fact document names its source in its opening citation line and in its Meta section, and Sources here links the official text (the Diário da República). The changes (the selection of provisions, the Markdown layout and the added anchors) are described in Meta. The corpus does not claim that the publisher endorses it, and only the officially promulgated text is authentic.
