The Europeanisation of Spanish Administrative Law through the Principle of Legitimate Expectations

This article describes the Europeanisation of Spanish administrative law as a result of the influence of the EU law general principle of legitimate expectations. It examines, firstly, whether the formal incorporation of the principle of legitimate expectations into national legislation and case law has modified the substance of the latter, and if so, secondly, whether this has led to a weaker or a more robust protection of the legal status quo. To carry out that examination, the article considers the influence of the principle of legitimate expectations in two different areas: in individual administrative decision-making, and in legislative and administrative rulemaking. Our conclusion is that the Europeanisation of Spanish administrative law through the principle of legitimate expectations has been variable and ambiguous.
