Fermionic first and second class constraints are covariantly separated, the first class constraints (1CC) turn out to be irreducible. We discuss also equations of motion in the covariant gauge for $κ$-symmetry. It is shown how the usual Fock space picture can be obtained in this gauge.19 pages, LaTex fileHigh Energy Physics - Theorytext
