Can someone help me with a link to an article, or a link to a SO post that contains a link, on why its not a good idea to model business rule violations with exceptions. I'd also be happy with a reference to a book and page, if the book was available on Safari, and an extract from the book would be double plus good!

**I've** seen plenty of good reasons in questions and answers I've looked at on SO, but others need something a little more authoritative (something in the Fowler/Evans league would be nice).

Thanks
