I think this is related to a laboratory returning false information, not to prosecutor malfeasance.
This could be ugly. The court costs reimbursement will affect the courts’ budgets. The restitution issue is complicated because it’s possible an exonerated victim of justice was forced to pay a private party, e.g., the victim of the crime in the case. Who should repay that reimbursement? the victim of the crime who was reimbursed? The state? The state BAR?
