Irish Legislation

One of the objectives of the Protocol on Ireland/Northern Ireland is to “maintain the necessary conditions for continued North-South cooperation” (Article 1(3)) and several of its provisions have direct or indirect implications for Ireland. In particular, Article 3 allows for the UK and Ireland to “continue to make arrangements between themselves relating to the movement of persons between their territories (the Common Travel Area (CTA))”. Implementing these aspects of the Protocol therefore require amendments in Irish law to enable the continuation of North-South cooperation and the CTA in the changed legal environment that results from UK withdrawal from the EU. 

On 10 December 2020, the Irish Government passed the Withdrawal of the United Kingdom from the European Union (Consequential Provisions) Act 2020 to make those legislative changes arising from the UK-EU Withdrawal Agreement – including the Protocol – or the UK’s withdrawal from the EU more generally. This ‘Brexit Omnibus Act 2020’ followed the Withdrawal of the United Kingdom from the European Union (Consequential Provisions) Act 2019 which was passed on 17 March 2019 as part of the Irish Government’s preparations for a possible ‘no-deal’ Brexit. The 2019 Act consisted of 15 parts – the majority never came into force – those aspects that were enacted are noted below for reference.

The Brexit Omnibus Act 2020 Act has 22 parts and impacts the portfolios of 11 Ministers/Departments in the Irish Government. An overview of the content is set out below, followed by links to secondary legislation where this has been made under the Brexit Omnibus Acts or under any other primary legislation but which relates to implementation of the Protocol.
