Abstract: BRST quantization is carried out for a model of p-branes with second-class constraints. After extension of the phase space, the constraint algebra coincides with the one of null string when p =1. It is shown that in this case one can or cannot obtain critical dimension for the null string, depending on the choice of the operator ordering and the corresponding vacuum states. When p>1, operator orderings leading to critical dimension in the p=1 case are not allowed. Admissible orderings give no restrictions on the dimension of the embedding space–time. Finally, a generalization to supersymmetric null branes is proposed.
