No specific laws identified for this ruling.
On remand, the Michigan Supreme Court addressed compensability of mental disorders under Workers' Compensation. In Deziel, the WCAB found disability but denied compensation because employment did not aggravate pre-existing condition. In Bahu, the WCAB reversed and awarded compensation, finding employment aggravated internal weakness to produce injury.
What This Case Was About
Two Michigan workers, Deziel and Bahu, filed workers' compensation claims for mental health conditions they said were caused or worsened by their jobs. Both had pre-existing mental health issues, but argued that workplace stress made their conditions worse and prevented them from working.
What the Court Decided
The Michigan Supreme Court reached different conclusions for each worker. In Deziel's case, the court found that while he had a disability, his job did not actually make his pre-existing mental condition worse, so he could not receive workers' compensation benefits. However, in Bahu's case, the court ruled that workplace conditions did aggravate her existing mental health problems enough to cause an injury, making her eligible for compensation.
Why This Matters for Workers
This ruling clarifies an important distinction for workers with mental health issues. Having a pre-existing mental health condition doesn't automatically disqualify you from workers' compensation, but you must prove that your job actually made the condition worse - not just that you have the condition and work is stressful. Workers need strong medical evidence showing their workplace specifically aggravated their mental health problems to qualify for benefits.
