Arguing Counsel

Panel That Day

3 of 4 cases argued January 28, 2025 before this panel have been decided.

Authorship Outlook

With the 3 decided siblings already credited to Chief Judge Diaz and Judge Quattlebaum, the remaining opinion is most likely Judge Rushing's — they wrote at least one opinion in 75 of their 109 prior multi-case days.

3 of the 4 opinions from this panel have been decided. Decided opinions have been authored by Chief Judge Diaz and Judge Quattlebaum.

This is a statistical guess based on prior sittings in this dataset, not a prediction of the ruling.

Predicted Opinion Release

Likely between November 16, 2026 and December 30, 2028, with March 23, 2027 the most likely date.

Argued 638 days ago. The case has now outlasted nearly every comparable prior case (97% of mass consumed); a separate writing or a contentious majority is likely in progress.
