William Rehnquist,
Siegert v. H Gilley — Opinion of the Court
“ Decision of this purely legal question permits courts expeditiously to weed out suits which fail the test without requiring a defendant who rightly claims qualified immunity to engage in expensive and time consuming preparation to defend the suit on its merits. One of the purposes of immunity, absolute or qualified, is to spare a defendant not only unwarranted liability, but unwarranted demands customarily imposed upon those defending a long drawn out lawsuit. ”
