When a parent challenges the validity of a release of parental rights on the ground that it was not made knowingly or voluntarily, the parent alleges a concrete injury arising from the trial court’s order and qualifies as an aggrieved party for purposes of appellate jurisdiction.

The Michigan COA has ruled that it did not have jurisdiction to hear the appeal in a child-welfare case because trial counsel filed the appeal, and not the father whose parental rights were terminated.
