In this paper we investigate the relation between the multiplicity and the tight closure of a parameter ideals. We shall show that local rings having a parameter ideal whose multiplicity agrees with the colength of its tight closure are Cohen-Macaulay rings.

We construct two examples of nonexcellent local Noetherian domains which demonstrate that tight closure and completion do not commute.
