what is lex specialis?

Answer 1

You can find some references to it in Google or Yahoo.

It does not appear in the English Wikipedia, but here's a rough translation of what the German Wikipedia says on the topic (http://de.wikipedia.org/wiki/Lex_specialis):

"A lex specialis is a special law that supersedes a lex generalis (general law). This special law displaces the general law. This law can result from the fact it governs only a special field, while the general law applies to several fields. For example, the law governing public gatherings is a lex specialis (special law) with respect to the general police law."
