Taylor Swift's Flight Tracker Doesn't Anticipate Authorized Struggle, Calls BS

But Slater retaliated last month … saying Taylor’s camp cited no law supporting the cease and desist — while also rebuffing the stalking claims … saying it doesn’t apply to his client whatsoever since Sweeney has never made a “credible threat” against Taylor through his words or actions.

He also pointed out the obvious … Sweeney simply uploaded publicly available data from the Federal Aviation Administration to track Taylor’s plane movements — a point backed by aviation attorney Tim Loranger of Wisner Baum, who tells us this has been a longtime hobby for aviation buffs … insisting there’s no there-there to threaten a lawsuit or any legal action.

Loranger tells TMZ that whether aircraft owners like it or not … their planes and jets have to be registered with the FAA and their registration numbers are displayed on their aircraft’s side … making it pretty easy to be followed on flight tracking services.

We spoke to some more legal experts who weighed in on Swift vs. Sweeney — and not everyone thinks he’s in the clear. Civil attorney Tre Lovell of The Lovell Firm tells us that unless Sweeney can clearly describe the purpose for his actions … he’d suggest Sweeney treads very carefully moving forward.

In contrast, Camron Dowlatshahi of Mills Sadat Dowlat LLP says TS has no legal standing in this matter — but the one thing she’s got is a whole lotta $$$ to bury JS in legal fees — so, bottom line, he should probably watch his back.
