A core feature of the Protocol on Ireland/Northern Ireland is the regulatory alignment of the UK 'in respect of Northern Ireland' with EU legislation and other EU acts concerning customs and the free movement of goods. The applicable legislation and other acts are listed in Annexes to the Protocol. Where a listed act is amended or replaced by a decision of the EU, the act as amended or replaced automatically applies in the UK in respect of Northern Ireland. Where the EU adopts a new act deemed relevant to the Protocol, the EU and the UK decide whether to add it the relevant annex to the Protocol. This is done by Decision of the Joint Committee.

The Joint Committee also has responsibility for taking a number of Decisions relating to the operation of the Protocol. These include the definition of goods entering Northern Ireland from outside the EU that are deemed 'not at risk' of onward movement into the EU and so are exempt from any applicable tariffs, also the levels of permissible financial support for the agricultural and fisheries sectors in Northern Ireland, and the arrangements for EU monitoring of UK implementation of EU law in Northern Ireland.

The Decisions relating to the Protocol taken by the Joint Committee are listed below. Also listed are joint declarations and the unilateral declarations that the UK and the EU have made regarding the implementation of the Protocol. Many of these relate to the Windsor Framework(2023).
