Direct attack

A direct attack on a judgment or decree is an attempt, for sufficient cause, to have it annulled, reversed, vacated, corrected, declared void, or enjoined, in a proceeding instituted for that specific purpose, such as an appeal, writ of error, bill of review, or injunction to restrain its execution; distinguished from a collateral attack, which is an attempt to impeach the validity or binding force of the judgment or decree as a side issue or in a proceeding instituted for some other purpose.
