Abstract: 
 We present a general method for obtaining solutions  for an
 abstract class of hemivariational inequalities. This result
 extends many results to the nonsmooth case.
 Our proof is based on a nonsmooth version of the Mountain Pass
 Theorem with Palais-Smale or with Cerami compactness condition.
 We also use the Principle of Symmetric Criticality for locally
 Lipschitz functions.
