European Union Bill

We turn now to decisions on which a referendum would always be required. Decisions taken in accordance with the Treaty provisions listed in clause 6 would always require approval by Act of Parliament and a referendum. One group of decisions covered by clause 6 are the one-way, irreversible decisions that would transfer competence from the United Kingdom to the European Union, including a decision that the UK would participate in a European public prosecutor's office, which can be set up to combat crimes affecting the EU's financial interests. Should the UK ever take part in the European public prosecutor following such a referendum, the decision that this country should take part in any expansion of the powers of that prosecutor is also listed in clause 6 and would therefore also be subject to primary legislation and a referendum.
