Exceptio Probat Regulam
An exception proves the rule.
Origin:- Republican Rome where it meant to be ‘The exception of a rules implies that there is a general rule in the first place’.
Henry Watson Fowler- Cited that the presence of an exception applying to a specific case establishes (“proves”) that a general rule exists. As per him, more explicit phrasing might be “the exception that proves the existence of the rule.”
Tracing its origin, it is thought to have emerged from the legal phrase “exceptio probat regulam in casibus non exceptis“, an argument attributed to Cicero in his defence of Lucius Cornelius Balbus. This argument states if an exception exists or has to be stated, then this exception proves that there must be some rule to which the case is an exception. The second part of Cicero’s phrase, “in casibus non exceptis” or “in cases not excepted,” is almost always missing from modern uses of the statement that “the exception proves the rule”, thus, creates confusion and gets misinterpreted
