Best 3 answers to "Why's there always an exception to a rule?"

A question was raised by Jonathan Magdaraog Villanobos: Why is it that, in every rule, there is an exception? Project Jurisprudence thinks this is a good question. No less than the Supreme Court affirms this idea. The High Court has held, "It is past dispute of course that in every rule, there are always settled exceptions." (G.R. No. 153578; January 28, 2005)
