I managed to remove someone as POA, however, she is still telling people she’s the POA and even brought a doctor into the care facility to see the charge. Thankfully the home realized and asked her to leave (the doctor). The new POA has arranged a doctor so my loved one is being well looked after. In order for the ex-POA to have arranged the doctor to come, would she have needed to prove she was POA to the doctor? Has she acted illegally even though the doctor didn’t see the charge?
The new POA may claim that he/she had no idea he/she had been removed as POA and there is of course nothing to prove otherwise unless she was legally served and notified.
None of this is as easy as saying "Hi, I am the POA". These things are WRITTEN in black and white. And when one things is changed then every single thing has to be changed.
Whether it was legal or not, her claim that she had no idea she no longer was MPOA and saw a need for help will likely have her excused in court this time.
Fraud is an iffy area of law; the standards are specific but sometimes vague (even though that doesn't always make sense), and fraudulent verbal and/or written representations or conclusions shouldn't be made by anyone except an attorney qualified in the area of fraud.
What would you consider doing if this individual actually did commit fraud? Would you be filing a police report? Elder abuse report?
If #1 is aware that she is no longer DPOA, then as Geaton suggested, get a lawyer to send her a letter to cease and desist. I would also make sure anyone #1 dealt with for Mom be made aware she is no longer POA by sending them a copy of the letter revoking her. Also, maybe giving info about the new POA.
