Yep. Time to lawyer up and sue the ever-livin' fuck out of the city of Philadelphia, and the state of Pennsylvania for permitting this to happen in the first place.
Seriously. The city tax office admitted to making up the $280K back taxes bill out of whole cloth, and because the guy, who lives on a fixed income, didn't purchase the transcript that some petty bureaucrat ordered him to, a fucknugget sitting on the bench and claiming to be a judge ruled that the guy had to pay the bill that everybody involved admitted he didn't owe.
I'm pretty sure that suing the city for a few tens of millions of dollars, with the lawyer paid half of the proceeds, would get him a damn good one willing to work without retainer.
