In a new lawsuit claiming $30 million in damages, a prominent personal injury firm, Ginarte Gallardo Gonzalez & Winograd, is alleging two competitor law firms enticed clients to switch attorneys by offering them Uber rides from a doctor’s office and then money from a briefcase full of cash in a partner’s office.

New York courts have seen several scandalous spats among personal injury law firms. However, the lawsuit filed Monday in Manhattan Supreme Court includes especially remarkable claims, such as competitor attorneys using “case runners” to meet clients at a pain management specialist’s office, then luring them to their firm and finally paying them off in cash if they agreed to substitute counsel.
