Montgomery Blair Sibley says he litigates “like a hurricane,” and he certainly has left a lot of legal wreckage in his wake. If you cross him, he’ll probably sue you. Just ask his ex-wife, Florida prosecutors or even Supreme Court justices, whom he sued for treason.

Sibley, 50, now represents the infamous Deborah Jeane Palfrey, who is accused of running a high-end D.C. prostitution ring. Sibley was brought in to recover more than $1.5 million in assets seized as part of the government’s criminal investigation. While Palfrey’s court-appointed criminal defense attorney has avoided headlines, Sibley has basked in the limelight, threatening to sell Palfrey’s 10,000-plus client list to pay her legal bills.
