St. John's Military School in Salina wants to split up a federal lawsuit in which 11 former cadets alleging the school fostered a culture of abuse.
Lawyers for St. John's argued in a recent filing the defense would be harmed by failure to hold 11 separate trials.
The motion contends each ex-cadet's claims are unique, and that a jury weighing all the claims in a single trial could get confused.
Attorneys for the plaintiffs say the school's attempt to pursue 11 trials would result in protracted litigation, with similar witnesses and documents throughout.
They argue a jury must hear about all of the alleged abuse to decide on punitive damages.
The lawsuit alleges the school encouraged higher-ranking students to discipline younger ones, leading to abuse.
Trial is set for March.
