Boddington v British Transport Police

On appeal, the question was whether Mr Boddington was entitled to raise, as a defence, the invalidity of the by-law under which he had been convicted. The difficulty was that the normal path for having an administrative action declared unlawful and invalid is an application for judicial review – which Mr Boddington had not brought.

The House of Lords held unanimously that he was entitled to bring a so-called collateral challenge in the criminal proceedings. Lord Irvine, then Lord Chancellor, and Lord Steyn gave the leading speeches. On the facts, however, Mr Boddington's challenge failed, and his appeal against conviction was dismissed.

Collateral challenges are an important means, alternative to an application for judicial review, of attacking the validity of an administrative action. Although collateral challenges had been permitted in English law before Boddington, the case is notable for strongly asserting their continuing relevance in modern law and rooting them in liberal values.

Boddington was adopted into South African law by the Supreme Court of Appeal in Oudekraal Estates (Pty) Ltd v City of Cape Town and Others.^[1]
