A federal judge signaled she may dismiss Trump's $10 billion lawsuit against the IRS, raising a fundamental problem: the president is suing government agencies he directly controls, which means there's no genuine legal adversary on the other side. Judge Kathleen Williams ordered Trump's lawyers and the Justice Department to explain why the case should be allowed to proceed at a May hearing. This creates a structural trap — the DOJ is legally required to defend the IRS, but Trump (as president) can direct the DOJ's strategy, making it impossible to have the genuine opposing sides required by law. Former government officials have already warned the court that this setup invites collusive litigation.
