    From locality and the spectral condition, general asymptotic causality properties of chronological \(N\)-point functions (or of \(N\)-particle collision amplitudes in massive theories, resp.) are derived. Results on rates of exponential fall-off of generalized Fourier transforms outside their microsupports are obtained, too.
