N2 - It is shown that the existence of null-plane charges and null-plane Fourier transforms (which enter into the discussion of current algebra at infinite momentum) depends on the high energy asymptotic behaviour of off mass shell scattering amplitudes; s In s behaviour is the maximum growth allowed. Under the assumption that asymptotic states exist, these results also hold in the case of spontaneously broken chiral symmetry with massless pseudoscalar Goldstone bosons. In this case, the resulting charges are the non-conserved pole-free charges suggested by Carlitz et al.
