A Pair of Briefs [1962] [DVD]

A recently-qualified barrister is annoyed when he finds his firm is taking on the boss' niece. The two youngsters soon find themselves in court on opposite sides in a case on the restitution of conjugal rights where the plaintiff and the defendant seem to have things to hide. The irascible and rather fearsome judge has little time for the goings-on, least of all, the way the two young lawyers seem rather too keen to squabble with each other ~ imdb

A fantastic supporting cast includes Roland Culver, Ron Moody, Liz Fraser, Bill Kerr and Joan Sims.
