The general context of this paper is the locality problem in quantum theory. In a recent issue of this journal, Rédei (1991) offered a proof of the proposition that algebraic Lorentz-covariant quantum field theory is past stochastic Einstein local. We show that Rédei's proof is either spurious or circular, and that it contains two deductive fallacies. Furthermore, we prove that the mentioned theory meets the stronger condition of stochastic Haag locality.
F. A. Muller has benefited from conversations with Professor Jan Hilgevoord on Haag's book and was inspired to write part (d) of sec. 4 after discussions with Dennis Dieks.
