In a Vietnam veteran's appeal concerning whether the U.S. Court of Appeals for Veterans Claims has authority to certify a class for class action or for similar aggregate resolution procedures, the Veterans Court denial of a motion to certify a class of thousands of veterans alleging service-connected post-traumatic stress disorder, diabetes, hypertension, and strokes, on grounds that it lacks authority to certify classes of claims, or to adjudicate disability claims on an aggregate basis, is reversed where the Veterans Court has the authority to certify a class for a class action and to maintain similar aggregate resolution procedures.
