Mohammad Tajsar is a civil rights attorney with the American Civil Liberties Union (ACLU) of Southern California, known for his strong advocacy on behalf of marginalized communities. His work focuses on protecting the civil liberties of immigrants, religious minorities, and people of color, especially when these rights are threatened by government overreach or discriminatory enforcement practices.
Tajsar specializes in areas such as immigrants’ rights, racial justice, national security, and government surveillance. As a lead attorney at the ACLU of Southern California, he has been involved in numerous high-profile cases that challenge the actions of federal and local authorities, particularly when constitutional rights are at stake. He regularly represents clients who allege racial profiling, unlawful detention, and denial of legal counsel by immigration officials or law enforcement officers.
Educated at UC Berkeley School of Law, Tajsar has developed a deep expertise in constitutional law, especially concerning the First and Fourth Amendments. His legal training and courtroom experience have made him a prominent figure in civil liberties litigation in California and beyond. Over the years, he has spoken out against practices such as racial and religious profiling, secret surveillance programs, and the misuse of law enforcement powers to target vulnerable communities.
One of Tajsar’s most recent and notable involvements includes his work in a federal lawsuit filed in Los Angeles in July 2025. In this case, civil rights attorneys accused immigration agents of conducting unlawful arrests based on race, ethnicity, and employment status. Tajsar argued in court that Latino individuals were being disproportionately stopped and questioned by immigration officers without reasonable suspicion. He pointed to reports that agents were making arrests at bus stops and work sites, often without clear evidence or proper warrants. This lawsuit led to a federal judge issuing two temporary restraining orders that significantly limited the ability of immigration officials to make stops based solely on racial or situational factors. The court also ordered that detainees must be provided with access to legal counsel seven days a week.
Tajsar’s legal efforts are not limited to immigration enforcement. He has also been a strong advocate against government surveillance programs that target Muslim communities. In several cases, he has argued that law enforcement agencies have infringed on religious freedoms and privacy rights by deploying informants in mosques or collecting data without warrants. These efforts have earned him recognition among civil rights groups and within legal circles committed to upholding the Constitution.
Aside from his courtroom work, Tajsar is active in community outreach and education. He regularly participates in public forums, panel discussions, and legal workshops to inform the public about their rights under U.S. law. He also works closely with local organizations and grassroots movements to provide legal guidance and build public awareness around civil liberties issues.
His media presence reflects his role as a trusted legal voice on matters involving government accountability and constitutional rights. Outlets such as the Los Angeles Times, NPR, and The New York Times have featured his commentary, especially in connection to immigration policies and surveillance reforms. Tajsar often emphasizes the importance of transparency, due process, and equal treatment under the law in all his public engagements.
Throughout his career, Mohammad Tajsar has used the law as a tool to push back against discrimination, uphold civil rights, and demand accountability from those in power. Whether representing individuals who were unlawfully detained or challenging systemic injustices through litigation, Tajsar continues to play a crucial role in the fight for justice and equality in the United States.
