Following law school, Dhillon clerked for Judge
Paul V. Niemeyer of the
U.S. Court of Appeals for the Fourth Circuit from 1993 to 1994. For the next ten years, Dhillon became an associate at a number of law firms before becoming a managing partner at the law firm named for herself, Dhillon Law Group, which was founded in 2006. The suit was settled in December 2018, with Dhillon arguing that it had forced the university to change its policies about controversial speakers, whereas the university maintained that it had already been following the amended policies before. although Dhillon has already lost an appeal to the
National Labor Relations Board. Damore's lawsuit against Google also was dismissed pursuant to a mandatory arbitration clause; however, the case continues without him. Conservative social media influencer and activist
Andy Ngo retained Dhillon as his attorney after being assaulted on the street in
Portland, Oregon, in June 2019. In June 2020, Dhillon filed suit on behalf of Ngo against
antifa seeking $900,000 in damages for assault and emotional distress, and an injunction to prevent further harassment. The lawsuit cited
Rose City Antifa, five other named defendants, and additional unknown assailants. It stemmed from multiple alleged attacks on Ngo in Portland during 2019 and accused Rose City Antifa in particular of a "pattern of racketeering activities". He subsequently lost the lawsuit when the jury did not find enough evidence to support his claim.
COVID-19 pandemic During the
COVID-19 pandemic in California, Dhillon was behind many lawsuits challenging the state's response to the pandemic including restrictions imposed by stay-at-home orders. She criticized California's decision to send mail-in ballots to all registered voters for the 2020 election and, regarding California’s approach to the pandemic, she asserted it uncovered its propensity to overreach, “The Constitution is not suspended in a pandemic, any more than it was suspended in every war that we’ve had in this country.’’ In May 2020, Dhillon criticized Virginia for requiring the use of face masks in public. She claimed that "the masks don't work" (contradicting the recommendation of health experts and the US CDC). In June 2020, she criticized California for requiring the use of face masks in public when individuals were unable to physically distance. She argued that people should be free to make their own decisions. She filed a lawsuit against Hawaii when the state required that visitors to Hawaii undergo quarantine upon arrival. In July 2020, a judge ruled that the emergency mandate was a reasonable response to the public health threat posed by the coronavirus. On April 17, 2024 Dhillon testified in front of the House Judiciary Committee to demonstrate the supposed violations of
civil rights that took place during the Covid pandemic. She argued that during the pandemic that fundamental rights were taken simply because the government declared an emergency. Dhillon expressed that she was alarmed that an emergency, when perceived by the government as such, could lead to such an abrupt “erosion of our freedoms and the complete disregard for the judicial scrutiny the courts use to preserve them in every other instance.”
Detransitioning case On February 22, 2023, Dhillon's firm filed a lawsuit against
Kaiser Permanente over misinforming and medical damage experienced by
Chloe Cole, a 18-year-old
detransitioner of Central Valley, California. The letter of intent to sue — addressed to Kaiser, a named endocrinologist, a named psychiatrist, and a named plastic surgeon — claimed that Cole suffers from ongoing health effects from
off-label use of prescription drugs. Cole says she was not properly informed as to potential negative effects of the
puberty blockers and
testosterone she was given at age 13. She also had a
double mastectomy as a
gender-affirming surgery at age 15 (legal in California). The lawsuit claims that Cole did not give
informed consent and that she was under extreme duress to accede to the medical treatments.
Legal representations Trump 2020 campaign legal adviser She was a legal adviser on the Trump 2020 campaign. While the Trump campaign was making claims of voter fraud during the 2020 election (as the ballots were being counted), Dhillon said the campaign was hoping that the
U.S. Supreme Court, including Trump-appointed justices such as
Amy Coney Barrett, would help Trump win the presidency.
Carlson lawsuit In 2023, Dhillon was hired by
Tucker Carlson to represent him in a gender discrimination lawsuit filed by former Fox News producer
Abby Grossberg. == Political career ==
