Ian Samuel, an Indiana University law school professor and host of the popular “First Mondays” podcast on the Supreme Court, has been placed on leave pending a Title IX investigation, the school said Dec. 3.

Chuck Carney, a university spokesman, confirmed the investigation and Samuel’s status, but declined to comment further.

Under Title IX of the 1972 Education Amendments, an “education program or activity” receiving federal funds can’t engage in sex harassment or discrimination.

The school emailed students, informing them that Samuel voluntarily admitted himself into a hospital.

Separately, the “First Mondays” podcast announced that Samuel “will be on a leave of absence” from the program “while he tends to personal and family issues.”

He didn’t immediately return a request for comment.

Samuel clerked for Supreme Court Justice Antonin Scalia but has espoused progressive views, including his proposal to “pack” the high court as a way to “fight back” against “right wing dominance of the court.”

He also helped spike a law firm’s requirement that associates agree to arbitrate claims, including sexual harassment disputes, instead of pursuing them in court. Such requirements have faced increased scrutiny since the development of the #MeToo movement.

Samuel tweeted pictures of Munger, Tolles & Olson’s employee arbitration agreements in March, noting that incoming summer associates at the firm would have to arbitrate potential harassment claims.

The firm dropped the arbitration clause a day later.
