It is a principle of parliamentary sovereignty that Parliament’s law making powers are not subject to any restriction, and therefore Parliament cannot bind its successors (see e.g. Dicey: “Parliament has, under the English [sic] constitution, the right to make or unmake any law whatever; and, further, that no person or body is recognised by the law of England [sic] as having a right to override or set aside the legislation of Parliament.”)
It follows that where two Acts of Parliament are inconsistent with each other, the courts will take the most recent one to be authoritative, through a doctrine of “implied repeal”.
However, in recent years, it has become accepted that certain statutes have, or have assumed, constitutional status, such that they are immune from implied repeal – examples being including: Magna Carta 1297, the Bill of Rights 1688, the Human Rights Act 1998 (notably, the European Communities Act 1972 was also felt to be one such, which opens up a whole new debate). Lord Justice Laws’ judgement [what a great set of words there] in Thoburn v Sunderland City Council [2002] EWHC 195 (Admin) is sometimes taken to be the definitive explanation of this.
What I’d missed, during the passage of the Data (Use and Access) Bill through Parliament, was the report of the Select Committee on the Constitution, which gave its opinion that the insertion of new section 183A into the Data Protection Act 2018 conferred constitutional statute status on that Act.
Section 183A provides that
A relevant enactment or rule of law which imposes a duty, or confers a power, to process personal data does not override a requirement under the main data protection legislation relating to the processing of personal data [except where] a relevant enactment [forms] part of the main data protection legislation [or] an enactment makes express provision to the contrary referring to this section or to the main data protection legislation (or a provision of that legislation)
(so, unless a further enactment is part of the data protection legislation, or expressly repeals a provision of the existing data protection legislation, the latter is immune from implied repeal).
What the Committee says is this
the courts have generally considered certain acts of Parliament to be of such constitutional significance that they should be treated as ‘constitutional statutes’ and protected from implied repeal. Clause 105 in effect seeks to bestow a status equivalent to that of a ‘constitutional statute’ on the Data Protection Act 2018. We draw this to the attention of the House.
I’ve not seen much discussion of this, and I don’t recall it coming up in the parliamentary debates. But it strikes me as interesting, at least.
