The author coniders a one-sided problem for a second order elliptic operator in a bounded domain $$\Omega$$ with a $$C^ 2$$-boundary, proving the existence of a solution of class $$\cap_{1<p<\infty}W^ 2_{p,loc} (\Omega)\cap C^{0,1}({\bar \Omega})$$ under certain conditions on the coefficients of the operator and on the closed convex sets associated with the problem.
