Consideration of and voting for this Bill do not constitute a breach of the law. However, there are powers in the Bill which, if and when exercised, will operate to disapply treaty obligations at the international law level—in particular, article 4 of the withdrawal agreement, and articles 5 and 10 of the Northern Ireland protocol. Parliamentary supremacy means that it is entirely constitutional and proper for Parliament to enact legislation, even if it breaches international treaty obligations. I am glad that my right hon. Friend voted in support of section 38 of the European Union (Withdrawal Agreement) Act 2020, which made it clear that parliamentary supremacy will prevail over international law.
