We prove that strict complementarity, primal and dual nondegeneracy of opti
mal solutions of convex optimization problems in conic form are generic pro
perties. In this paper, we say generic to mean that the set of data possess
ing the desired property (or properties) has strictly larger Hausdorff dime
nsion than the set of data that does not. Our proof is elementary and it em
ploys an important result due to Larman [7] on the boundary structure of co
nvex bodies.
