Judge William D. Lehman

Judge William D. Lehman has served on the Imperial County Superior Court since 2006, following a gubernatorial appointment by Governor Arnold Schwarzenegger to fill the vacancy left by the retiring Hon. Matias Contreras. His judicial profile is shaped most distinctively by his unusually deep roots in Imperial County's legal community — a factor that carries significant implications for how he approaches courtroom dynamics, local practice norms, and attorney credibility. Before ascending to the bench, Judge Lehman spent over two decades in the Imperial County Public Defender's Office, rising from deputy to assistant public defender over a twenty-one year tenure. This career arc strongly suggests a judge with substantial criminal defense experience, a nuanced understanding of indigent representation, and firsthand familiarity with the pressures and realities of public sector legal work. His 2004 appointment as a court commissioner provided an additional two years of judicial seasoning before his full elevation in 2006, meaning he has now spent roughly two decades as a judicial officer in the same county where he practiced law. Judge Lehman's educational background — undergraduate at California Lutheran University and law degree from the University of San Diego School of Law — reflects a practitioner-oriented legal education rather than an academic or elite-firm pipeline. Combined with his career trajectory, this suggests a judge who values practical, grounded legal argument over abstract theory. His long tenure in a small, close-knit court system like Imperial County likely means he has developed consistent procedural expectations and a well-established courtroom culture. Attorneys unfamiliar with local practice norms in Imperial County should invest significant effort in understanding the informal expectations of this court, as deviation from established local customs may be viewed less favorably than in larger, more anonymous urban courts. No specific ruling analyses are available to confirm particular doctrinal tendencies, so all assessments are inferred from career background and appointment history.

Attorneys appearing before Judge Lehman should prioritize demonstrating genuine familiarity with Imperial County's local rules and courtroom culture. Given his twenty-one years as a public defender in this same jurisdiction, Judge Lehman has an exceptionally long institutional memory and likely has strong views about professional conduct, candor, and the practical realities of local practice. Attorneys who appear to be parachuting in from larger metropolitan markets without adequate preparation for local norms risk losing credibility quickly. Conversely, attorneys who demonstrate respect for the local legal community and its customs are likely to be received more favorably. In criminal matters specifically, Judge Lehman's extensive public defense background is a critical strategic consideration. He has spent the majority of his legal career advocating for defendants, which may translate into heightened sensitivity to due process concerns, proportionality in sentencing, and the practical burdens placed on defendants and their families. Prosecutors should be prepared for a judge who understands defense arguments from the inside and will not be easily persuaded by boilerplate prosecution positions. Defense attorneys, meanwhile, should not assume automatic sympathy — a former public defender on the bench often holds defense counsel to a high standard of preparation and advocacy, precisely because they know what good defense work looks like. For civil matters, where Judge Lehman's background provides less direct inference, attorneys should focus on clear, well-organized briefing and realistic, practical arguments. Avoid overly academic or theoretical framing. Emphasize factual grounding and equitable outcomes. Given the small size of the Imperial County bar, maintaining a professional and collegial tone — even in adversarial proceedings — is likely to serve attorneys well.
