On Tuesday, Prince Harry lost his security battle against the Home Office over his security arrangements during his visit to the UK.
The Duke of Sussex sued the Home Office on the decision not to allow him to pay for his security.
Harry is unable to bring a second High Court challenge against the Home Office.
The Home Office was always against the idea of getting paid by wealthy people to buy security from police forces.
A government spokesperson said: "We welcome the judgment upholding the integrity of the protective security system.
"The UK Government’s protective security system is rigorous and proportionate. It is our long-standing policy not to provide detailed information on those arrangements, as doing so could compromise their integrity and affect individuals’ security.
"It would not be appropriate to comment further on the legal proceedings."
