A medical malpractice case is one of three potential jury trials topping the docket this month as the Dukes County Superior Court begins its fall session.

The twice-annual formal session of the superior court began Monday, and will run through the end of the month. The court has jurisdiction over most criminal cases in Dukes County, and civil cases where damages may exceed $50,000. Convening formally in April and October, the court hears other matters sporadically throughout the year.

The Hon. Janet L. Sanders will preside over four cases in total scheduled for the session this month.

Jury selection for a medical malpractice case involving Martha’s Vineyard Hospital surgeon Dr. Pieter Pil begins Tuesday. On Monday, attorneys for Dr. Pil and plaintiff Choying Rangdol set a schedule for the case and sought approval of vetting questions for jurors.

“I think a lot of people on the jury panel are going to know each other,” Judge Sanders said, referencing to the attorneys the small size of the Vineyard community.

The plaintiff alleges malpractice against Dr. Pil by way of negligence that led to an extended recovery time following an appendectomy, attorneys for Mr. Rangdol explained Monday. Dr. Pil is not a direct employee of Martha’s Vineyard Hospital, his attorney said, and the hospital is not a defendant in the case.

Another jury trial for a breach of contract case was scheduled for Oct. 24 during the court session Monday. William Mueller Plumbing of Edgartown is the plaintiff in the case against Richard Conrad.

A second breach of contract case between Ralph Packer and Mike and Mark Wallace is also scheduled this month.

Jury trials are currently slated for both breach of contract cases, though Dukes County clerk of courts T. George Davis said the likelihood of a jury trial is variable as attorneys negotiate the options for settlement and bench trial.

The fourth case on the docket, a land dispute between residents of Aquinnah and the Vineyard Conservation Society ,is slated for a bench trial next week, Mr. Davis said.

“There’s a question of who owns a particular parcel of land,” he said.

Also Monday, Rockwell Masonry owner Gregory Pyden was arraigned on worker’s compensation fraud and larceny charges. A statement issued by attorney general Maura Healey last month alleges Mr. Pyden stole over $30,000 in Workers’ Compensation Insurance from AIM Mutual Insurance Company and the Massachusetts Workers’ Compensation Assigned Risk Pool from 2016 to 2020.

Mr. Pyden pleaded not guilty to all charges Monday.
