Warren E. Burger,
Groppi v. Leslie — Opinion of the Court
“ Legislatures are not constituted to conduct full-scale trials or quasi-judicial proceedings and we should not demand that they do so although they possess inherent power to protect their own processes and existence by way of contempt proceedings. For this reason, the Congress of the United States, for example, no longer undertakes to exercise its contempt powers in all cases but elects to delegate that function to federal courts. ”
