Abstract: Let $ \Lambda $ be an Artin algebra. This paper presents a condition that is necessary for a subcategory of $ \bmod \Lambda $ to be contravariantly finite. Several examples are explored in the case that $ \Lambda $ is the group algebra of a finite group over a field of finite characteristic.
