Abstract
A simple general argument is given to show that the counterterms in the space-like planar gauge with the Cauchy principal value prescription for the spurious singularities are local. This result is used to obtain limitations on the number and on the kind of nonlocal counterterms occurring in the light-cone case with the Mandelstam-Leibbrandt prescription.
