The Information and Privacy Commissioner of Alberta, Frank Work, has authorized a company to ignore access requests as being vexatious. PIPA allows the Commissioner to authorize a company to ignore such requests. In this case, the individual had been involved in fifteen years of litigation with Manulife (the applicant). The company said it had no other information on the individual that had not already been handed over as part of the discovery process. The report of the Commissioner is availble here: http://www.gov.ab.ca/acn/200512/19181.pdf.
