Placement of footnote reference relative to closing quotation mark.

I insert alot of quotes into my text, and I like to use footnotes for citations. My question is where should I put the footnote relative to the closing quotation mark. For example, I might write somethin like: The Court held that "the alleged counduct, if true, would be a serious violation of the statue." Should I put my footnote reference before or after the closing quotation mark?

Thanks for your help!!!!

It should be placed outside the quote marks, since the footnote itself is not part of the matter quoted.
