The Coalition Protecting Auto No-fault (C-PAN) is in the process of taking The Michigan Catastrophic Claims Association (MCCA) to the Supreme Court.
The high costs of car insurance in Michigan sparked the lawsuit.
The MCCA covers medical costs for serious accidents totalling more than $530,000 in damages.
The association charges drivers $186 per car and is currently exempt from requests through the Freedom of Information Act or FOIA.
C-PAN argues that the association should not be exempt and records should be opened up to public scrutiny.
An Ingham County judge originally ruled in favor of C-PAN, ordering the MCCA to open up it's records to the public.
However, the MCCA appealed that decision and a 3-judge appellate panel agreed that the association is, in fact, exempt from FOIA requests.
The case is still underway.
