Abstract: In the talk it will be argued that the violation of the Bell inequality in algebraic quantum field theory do not exclude a common causal explanation of a set of quantum correlations if we abandon commutativity between the common cause and the correlating events.  Moreover, it will turn out that the common cause is local, i.e. localizable in the common past of the correlating events. It will be argued furthermore that giving up commutativity helps to maintain the validity of Reichenbach's Common Cause Principle in algebraic quantum field theory.
