More than 30 former federal judges have asked a federal judge in Florida to examine whether the administration’s reported $1.8 billion settlement resolving President Trump’s lawsuit against the IRS may constitute a “fraud on the court,” escalating what had appeared to be a closed dispute into a potentially significant fight over judicial integrity and executive-branch litigation conduct.

The filing is notable not because it decides anything on the merits, but because of who is making the request and what doctrine they are invoking.

A Texas state court has ruled that a judge may decline to perform same-sex marriages based on sincerely held religious beliefs, a closely watched decision at the intersection of judicial ethics, equal-treatment principles, and religious-liberty protections. The case stems from disciplinary action against Justice of the Peace Dianne Hensley, who challenged a public warning issued by the Texas Commission on Judicial Conduct after she said she would not officiate same-sex weddings.

For court watchers, the dispute has long been about more than one judge’s wedding calendar.
