The PALGA Foundation has established an independent Complaints Board for processing complaints. The Board’s task is to adjudicate on complaints by patients, messengers, pathologists, or any other interested parties, regarding the alleged infringement of an individual’s personal privacy, in the context of PALGA's database and any related work.
