Sometimes the introduction to the opinion (helpfully) says pretty much everything you need to know:
"In this case, the litigants seeking to compel arbitration initiated this lawsuit by filing a complaint in court and, while in the judicial forum, sought two forms of preliminary injunctive relief, opposed a demurrer, propounded more than 700 discovery requests, demanded a jury trial in their case management conference statement and represented they would be litigating substantive motions, and posted jury fees. It was not until the opposing party filed a cross-complaint that the litigants filed the motion to compel arbitration—more than six months into the litigation in court. Does the litigants’ conduct in this case constitute a waiver [of arbitration]? We conclude it does, and affirm the trial court’s order denying the motion to compel."
Thanks for that, Justice Hoffstadt.
