Carlos F. Concepcion of Shook, Hardy & Bacon has stepped into a U.S. Supreme Court battle on behalf of the Miami International Arbitration Society.

The Miami attorney filed an amicus brief in a case that asks what to do when one litigant is bound by a contract compelling arbitration, but the other is not.

If the dispute is domestic, then arbitration contracts win out, thanks to the doctrine of equitable estoppel, which says parties can't benefit from a contract they've signed unless they abide by its terms.
