The High Court has ruled the Metropolitan Police cannot dismiss officers by removing their vetting clearance.

London Mayor Sir Sadiq Khan said the ruling has "significant implications for the work the Met is now doing to clean up the force."

Sergeant Lino Di Maria successfully mounted a legal challenge, supported by the Metropolitan Police Federation, after having his vetting removed over sexual assault allegations, which he denies.

He was found to have no case to answer in respect of misconduct allegations, and argued that having his vetting removed without the accusations being proved is a breach of his right to a fair trial.

Justice Lang said: “In my judgment, the defendant’s powers do not extend to the dismissal of a police officer by reason of withdrawal of vetting clearance.

"Dismissal is a matter which should be provided for in regulations made by the Secretary of State. This results in an anomalous situation where officers who do not have basic vetting clearance cannot be dismissed by the defendant."

She continued: "In my view, that anomaly could and should be resolved by regulations."

Lawyers for the Metropolitan Police had previously told the court that a procedure under current performance regulations allowed officers to be dismissed if clearance was withdrawn.

However, Justice Lang said she did not consider this "fit for purpose" adding: "The process deprives the officer of any meaningful opportunity to challenge a finding of gross incompetence."

Justice Lang continued: "The panel merely confirms a decision that has already been made, by an internal vetting regime which is not Article 6 (right to a fair trial) compliant. Where basic vetting clearance has been withdrawn, the only outcome open to the panel is dismissal."

Sir Mark Rowley said the ruling has “left policing in a hopeless position”.

He told a press conference: “Today’s ruling on the law has left policing in a hopeless position. We now have no mechanism to rid the Met of officers who were not fit to hold vetting – those who cannot be trusted to work with women, or those who cannot be trusted to enter the homes of vulnerable people.

"It is absolutely absurd that we cannot lawfully sack them. This would not be the case in other sectors where staff have nothing like the powers comparable to police officers."
