Guide to the 2023 Review of Parliamentary constituencies
After the final report
After the final report from all four Parliamentary Boundary Commissions has been laid by the Speaker, within four months of the last report being laid, the Government is required to submit to the Privy Council an Order that gives effect to all four Commissions’ recommendations. In drawing up that Order, the Government may not modify any of the recommendations of the Commissions, unless specifically requested to do so by the relevant Commission (and any such request must itself be laid before Parliament and published).
After the Privy Council approves the Order, the new constituencies take effect at the next General Election. Any by-elections held in the meantime have to be held on the basis of the old (existing) constituencies. The validity of an Order in Council, once made, may not be called into question in any legal proceedings.
