Mr. Stris was one of just 20 private-sector attorneys to argue six or more cases before the U.S. Supreme Court over the period analyzed in a recent empirical study, achieving victories in cases interpreting the Copyright Act, the Securities Exchange Act, and ERISA. Peter has handled dozens of major appeals before appellate courts throughout America, with highlights including his revival of multibillion-dollar environmental claims against Volkswagen and reversal of dismissals leading to collected recoveries of $24 million for investors in one case and over $22 million for pensioners in another.

Recently, Peter won a multi-phase jury and bench trial that the Daily Journal named a Top 20 Defense Verdict of 2021. The plaintiff, represented by a respected AmLaw firm, had sought $180 million for Lanham Act false advertising.

Peter is currently serving as lead counsel in several noteworthy cases preparing for trial in courtrooms throughout America.

Strategic Litigation

Peter is often retained when an effective public communications strategy is critical. He is adept at managing evolving situations where messaging must be issued in real time. For example, Peter ran a notable litigation communications campaign that recovered his client’s life rights from the National Enquirer, allowing her to speak publicly about a 10-month relationship with President Donald Trump. Watch Peter’s TV appearances.
