Article 3 of Protocol No. 7 of the European Convention on Human Rights recognizes a right to compensation to the person affected by a firm criminal conviction later annulled for reasons unrelated to the convict. The present work explores the possibility that this right is also exercisable in the sanctioning administrative sphere, in particular, in relation to the annulment of firm administrative sanctions, as well as the consequences that this would have for the Spanish system of patrimonial responsibility of the Public Administration.
