1. The EU Referendum Act 2015 provided for challenge to the result within 6 weeks and on limited grounds. 2. PPERA provides criminal sanctions for breach of the spending rules, but not that breach provides a ground for invalidating the result. This is the same position as for
breach of national spending rules at a general election. 3. The referendum result was advisory and didn't specify any legal consequences; ergo nullification of the result would equally have no legal consequences. 4. Following the Miller case, the UK Parliament enacted
the EU (Notification of Withdrawal) Act 2017. It is this, rather than the referendum, that authorised the Art 50 notification, and the validity of the Act is not dependent upon the validity of the referendum. 5. Acts of Parliament cannot be invalidated by the courts.
