A lawyer who successfully sued the Bronx District Attorney’s Office for terminating a prosecutor after she started using a wheelchair isn’t satisfied with netting just 25 percent of his client’s $50,000 back-pay settlement.

The lawyer, Mark Moody, is now suing his former client, ADA Diana Lewis, for 25 percent of her salary, too.

Moody said he took the case on a contingency basis and that his and Lewis’ agreement to pay him 25 percent of her settlement should include her $70,000 salary, since he also “won’’ that back. Moody says he’s entitled as long as she’s employed by the Bronx DA.

“I gave him $13,000 and that was our . . . agreement,” Lewis told The Post.
