Can an attorney who multiplies the proceedings in any case unreasonably and vexatiously be required to pay personal costs or fees?

Under 28 U.S.C. Sec. 1927, "[a]ny attorney ... who so multiplies the proceedings in any case unreasonably and vexatiously may be required by the court to satisfy personally the excess costs, expenses, and attorneys' fees reasonably incurred because of such conduct." 28 U.S.C. Sec. 1927 (1982). Section 1927 authorizes a taxing of only those excess costs incurred by reason of "an attorney's unreasonable and vexatious conduct." United States v. Blodgett, 709 F.2d 608, 610 (9th Cir.1983). Moreover, section 1927 "does not authorize imposition of sanctions in excess of costs reasonably incurred because of such conduct." Id. at 610-11.
