JFS has lost its Supreme Court Appeal over its admissions procedure.
The Supreme Court judges were split 5-4 in the court’s most high-profile case since it opened.
The judges' ruling means that no faith school can have an admissions policy based on halachic status.
JFS were contesting a Court of Appeal decision made on behalf of a boy who had originally been rejected because the Chief Rabbi does not recognise his mother’s non-Orthodox conversion.
