A Boca Raton lawyer’s quixotic legal battle to have President Donald Trump declared unfit for office may be over.

The 4th District Court of Appeal on Thursday rejected attorney James Herb’s appeal of a Palm Beach County circuit judge’s decision that found his petition "wholly without merit." The West Palm Beach-based appeals court offered no explanation for why it rejected Herb’s appeal, simply affirming Circuit Judge Jaimie Goodman’s November ruling.

Herb, a probate and guardianship attorney, said he was disappointed the three appeals court judges who rejected his appeal didn’t write an opinion, explaining their reasoning. He said he plans to ask all 12 judges on the court to review the case in hopes they will intervene.

Neither Trump nor his attorneys responded to Herb’s claims that statements the real estate tycoon and part-time Palm Beach resident has made indicate he suffers from mental ills, such as histrionic and narcissistic personality disorders. Herb was asking that a panel of psychological experts be appointed to interview Trump to determine his mental state.

Herb acknowledged his petition faced numerous hurdles even if approved by the courts. First, Trump could refuse to meet with the panel. Further, even if he did and the panel found Trump suffered psychological ills, a circuit judge wouldn’t have the power to remove Trump from office. That could only be done by the vice president and the Cabinet under a procedure outlined in the 25th Amendment to the U.S. Constitution, he said.

Herb isn’t the only South Florida lawyer to take legal action in hopes of removing Trump from office. Broward County attorney Patrick Goggins in July filed a suit in U.S. District Court in West Palm Beach, claiming the president is violating the domestic emoluments clause of the U.S. Constitution because of the ongoing business dealings of the Trump Organization. The clause bars presidents from earning money beyond their government salary.

Goggins dropped the suit last week, wishing well to others who have filed similar lawsuits elsewhere. A federal judge in New York is considering claims filed by the liberal watchdog group, Citizens for Responsibility and Ethics in Washington, that Trump is violating both the foreign and domestic emoluments clause because Trump’s business empire is benefiting from his status as the leader of the free world.
