In this paper a class of semilinear elliptic optimal control problem
with pointwise state and control constraints is studied. A sufficient second
order optimality condition and uniqueness of the dual variables are assumed
for that problem. Sufficient second order optimality conditions are shown for
regularized problems with small regularization parameter. Moreover, error
estimates with respect to the regularization parameter are derived
