Administrative admonition in penalty proceedings is inadmissible as it lacks statutory basis under the specified decree-law article.

The Tribunal da Relação de Lisboa declared the appeal inadmissible because the administrative authority applied an admonition measure not foreseen in the relevant penalty proceedings law. The appellant challenged a sentence issued in a contraordenação process where the authority had imposed an admonition instead of a fine or other prescribed penalty. The court ruled that since the specific measure was not listed in Article 73 of the applicable decree-law, the administrative decision lacked legal foundation and the appeal could not proceed.
