Prince Harry Loses Court Battle Over UK Security, Downgrade Not Unlawful

10:41 AM PT -- A spokesperson for Prince Harry announced he will appeal this decision.

Prince Harry has been waging war with the British government over the fact they yanked his publicly-funded security in the UK ... but a judge flipped him the bird once and for all.

A decision was made in the drawn-out case that's been going on since 2022 -- with the London High Court ruling Wednesday in favor of the Home Office after PH had attempted to overturn a decision made that downgraded his level of protection across the pond.

Remember ... when he and his wife, Meghan Markle, stepped down from their Royal posts -- the red coats turned their back on them too -- revoking top-level police officer security details a full-time working Royal might normally be afforded. Harry cried foul and sued over this.

Like we said, this has been going on for a long time ... but it's finally reached its conclusion -- and the Duke's walking away with an L.A. judge saying there was nothing unlawful or unfair about the way this conclusion was reached by the Home Office.

There doesn't seem to be much detail in terms of the rationale here -- all the judge reportedly said in the docs was that this move was reasonable and legal ... and that the alternative for Harry -- a tailored, less formal security detail if/when he's in the UK -- is also appropriate.

Mind you, Harry had already lost another battle on this security front -- he had tried arguing that he should be able to pay for high-level cop security ... but he got turned down there too.

Harry's whole gripe boiled down to him feeling like his family wasn't safe in the UK if they couldn't get the royal treatment in terms of security -- and now, it sounds like the government and the High Court are flatly telling him ... you're not a Royal anymore, bro. Deal with it. 🤷🏽‍♂️
