> Investigation of fraud. A public accommodation may investigate the potential misuse of accessible seating where there is good cause to believe that such seating has been purchased fraudulently.

I don't know if there are any remedies available beyond civil tort and contract money damages, nor what the applicable criminal statute would be, if any. Seems like a complex area of law, but from reading bits of legal commentary dredged up with Google I get the impression that the government is deliberately erring on the side of reducing friction for the legitimately disabled and are well aware of the unintended consequence of increased fraud.
