NEW YORK -- During US President Donald Trump's first 100 days in office, California has on average challenged the administration in court more than twice a week, reported The Los Angeles Times on Tuesday.

The state has filed 15 lawsuits against the Trump administration, all but one alongside other states, and filed briefs in support of other litigants suing the federal government in at least 18 additional cases, according to the report.

"The state has won victories that have slowed Trump's agenda and could block some of his policies permanently," the report noted. "It has won multiple temporary restraining orders and preliminary injunctions blocking Trump policy measures, including a sweeping freeze of trillions of dollars in federal funding that Congress had already allocated to the states, and a Trump executive order to end birthright citizenship for the US-born children of certain immigrants."

California also has suffered losses in court, with judges in some instances allowing administration policies to take hold while the state argues for their ultimate reversal. Higher courts have reversed a couple of restraining orders sought by the state and granted by district court judges, including the one on teacher preparation grants and another that had halted Trump's mass firing of federal probationary employees.

Attorneys in California have been working at a blistering pace to draft and file complex legal arguments opposing Trump's policies on immigration, the economy, tariffs, LGBTQ+ rights, federal employee layoffs, government oversight, the allocation of federal funding to states and localities, the limits of the president's executive authority and the slash-and-burn budgetary tactics of his billionaire advisor Elon Musk, according to the report.
