I strongly suspect this is a typo for 学界.
Therefore this is nothing to do with meeting/gathering of scientific experts.
Because your subject is medical malpractice litigation, these experts opinions are being required and must be counted for.
I believe this is appropriate in your context.

Gathering from the example you gave, my feeling is that the term in question should be an expert panel---as in a panel established to form opinions based on medical experts (the term is also used in medicolegal studies). But like Takanori-san, I am uncertain what you're really asking. Hope this helps!

ack, it should be "as in a panel established to form guidelines based on expert opinions (the temr is also used in medicolegal studies)".

I would recommend going with Takanori-san if the expert group is an actual society/association as opposed to an ad-hoc establishment.

I've done some research on medical malpractice litgations in japan in reference to some expert panel. So now I'm getting it. The program is called the Model Project in which an ad-hoc evaluation committee is set-up to investigate cases of medical malpractice. See below:

"To address this unsatisfactory situation, responding to a proposal from four medical specialty societies, the Ministry of Health, Labor & Welfare in 2005 launched a 5-year “Model Project for the Investigation and Analysis of Medical Practice-Associated Deaths.” The Model Project, now operating in eight of Japan’s 47 prefectures including the most populous, is aimed at instituting impartial, high-quality peer review of possibly iatrogenic hospital deaths to provide accurate information to families and alleviate public concern about coverups of adverse medical events while in most cases avoiding police involvement.

When a patient dies in circumstances possibly related to medical management, the hospital, with the family’s consent, may apply to the Model Project’s regional office for an investigation. That office, on accepting a case, assembles a team of three physicians not connected with the hospital—a clinical pathologist, a forensic pathologist, and a specialist in the field of the patient’s treatment—to conduct an autopsy. A separate evaluation committee reviews the patient’s chart and the autopsy results, interviews hospital personnel, and prepares a report setting out the facts, a medical (not legal) evaluation of the course of care, and conclusions on how the adverse event could have been prevented. This report is shared with the hospital and family. A summary is made public with names of the patient, medical staff, hospital, and location masked [22]."
