About the Firm

Najvar Law Firm PLLC focuses on aggressive litigation, at trial and through the highest levels of the appellate process, including the United States Supreme Court.  We focus on defending fundamental liberties and advancing principles of limited, constitutional government. NLF has successfully litigated cases involving First Amendment, Fourth Amendment, and due process rights in various contexts, scoring landmark victories striking down federal and state laws, as well as municipal charter provisions and ordinances in various Texas cities. Some representative matters are summarized below.

NLF is not a volume litigation practice; instead, we focus intensely on a limited number of matters implicating important rights and issues. We also provide expert counsel regarding the dizzying array of federal and state political laws, including campaign finance, ethics, and election laws governing all aspects of the political process, as they affect candidates, officeholders, PACs, and nonprofits. This includes zealous representation in the Federal Election Commission, Texas Ethics Commission, and municipal ethics commissions.
