Judge Harold W. Hopp

Judge Harold W. Hopp serves on the Riverside County Superior Court, having been appointed by Governor Jerry Brown in 2017. In June 2023, he was appointed to the Judicial Council by the Chief Justice, reflecting institutional recognition of his judicial standing within California's court system. His docket has included both civil and criminal matters, demonstrating breadth across case types at the Riverside Historic Courthouse. The most prominent documented ruling attributed to Judge Hopp is a December 2024 decision finding that the City of Riverside was illegally using water revenues, a ruling that resulted in $37 million in refunds. This ruling demonstrates a willingness to rule against a municipal government on a significant public finance and utility law question, and to impose substantial monetary consequences. The record also reflects involvement in criminal proceedings, including a 2014 acquittal of a defendant in a case involving allegations of sexual conduct with a minor — indicating Judge Hopp has presided over high-stakes, sensitive criminal matters. Because no analyzed rulings, attorney observations, or ingested content are available beyond these profile data points, the depth of behavioral and stylistic intelligence on Judge Hopp is limited. Attorneys should treat the insights below as grounded in the documented facts available and supplement this profile with direct courtroom observation and local counsel consultation.

The December 2024 water revenue ruling demonstrates that Judge Hopp is willing to rule against governmental entities when the legal basis supports it. Attorneys litigating against municipal or public agency defendants in Judge Hopp's courtroom should not assume deference to the government position.

Judge Hopp's appointment to the Judicial Council in 2023 signals engagement with statewide judicial administration and policy. Attorneys should present arguments that are procedurally precise and consistent with California Rules of Court, as judges involved in judicial governance tend to hold courtroom practice to a high standard. Sloppy filings or procedural shortcuts are a risk in this courtroom. Given the limited data available, attorneys are strongly advised to consult with Riverside-based practitioners who have appeared before Judge Hopp, and to review any publicly available tentative rulings or minute orders from his department. Direct observation of his courtroom prior to a scheduled hearing is the most reliable way to supplement this profile.
