The city of Philadelphia has filed a lawsuit against Mylotte, David & Fitzpatrick and more than 60 past and present lawyers there, claiming that the law firm failed to pay more than $2.3 million in taxes, including interest and penalties.

But some lawyers named as defendants are upset because they claim they were never partners at the firm, while one said he never even worked at the firm. One of the taxes the city claimed wasn’t paid — the business privilege tax — is only applicable to partners. The other two taxes not paid, according to the lawsuit, were the net profits and city wage tax.
