Allow workers to be compensated for previous injuries which were undisclosed to worker, or which have given rise to uncompensated health issues.
Why is this important?
Injuries received on the job may cause health problems later on in life. Workers who find that previous injuries prevent them from obtaining employment, or giving rise to new health damages should be able to re-open their claims to receive their proper compensation. This will encourage insurance companies to insist on discovering/ disclosing all health outcomes to workers.
