Do residents of towns with a communal eruv cause the eruv to be invalidated when non-eruv-covered outsiders enter (e.g., come to pray at a synagogue)?
Synopsis
The Aruch HaShulchan addresses whether outsiders without eruv coverage can invalidate a community eruv, concluding they do not, since the 'forbidden foot' principle applies only in enclosed courtyards with no other exit.
