Relevant Experience


Weddle Law is ready to help individuals and businesses navigate the stresses and disruption of a criminal or regulatory investigation. Regardless of how an investigation comes to light—whether from a law enforcement contact or subpoena, a whistle blower complaint, an unexpected bank account closure, or a corporate internal investigation—we work hard to convert a reactive situation into a proactive strategy. Our experience and skill in conducting and defending investigations, as well as in courtroom advocacy, serve as a foundation for developing creative solutions to enforcement problems. We seek out available facts, conduct our own analysis, and develop a strategy calculated to reach the optimal outcome. We have successfully navigated diverse criminal, civil, and regulatory investigations toward closure with no action being taken against our clients.

At Weddle Law, we recognize that internal investigations are not an end in themselves, but a means to an end. We build teams with the necessary expertise for the issues presented and ensure that in conducting our work, the substance drives the process, not the other way around. Drawing on skills honed in conducting more than a hundred investigations involving voluminous documents and scores of potential interviewees, we focus in the key issues and execute our investigative plan to get to the facts quickly and efficiently. We couple those facts with analysis and craft a tailor-made strategy appropriate to the circumstances.

Justin Weddle has extensive appellate experience, and is regularly called upon to participate in some of the highest profile issues affecting the white collar defense bar. He has personally conducted twelve arguments in the U.S. Court of Appeals for the Second Circuit, and has helped craft more than eighty appellate briefs in diverse appellate courts, including the U.S. Supreme Court, and U.S. Courts of Appeals for the First, Second, Third, Tenth, Eleventh and D.C. Circuits. He is a regular participant in appellate challenges to the SEC’s Administrative Tribunals and the SEC’s disgorgement practices.

When the best strategy is to fight, we fight. There is no substitute for the proven ability and willingness to go to court and present the evidence. Justin Weddle has experience taking the most complex cases to trial—distilling simple, compelling narratives from sophisticated theories and financial transactions. Justin also leverages his extensive appellate experience to ensure that issues are presented and preserved during the trial.
