Champion's claim that it was improperly invited to make an oral presentation is not a challenge to a solicitation or other request for offers, the cancellation of such a solicitation or other request, an award or proposed award of a contract, or the termination of a contract based on improprieties in the award of the contract.  It therefore does not come within the scope of our bid protest jurisdiction.  31 U.S.C. §§ 3551(1), 3552; 4 C.F.R. § 21.1(a).  We recognize that we have previously considered a protester's assertion that its proposal should not have been included in the competitive range.  See, e.g., Global Indus. Servs., Inc., B-260287.2, July 18, 1995, 95-2 CPD ¶ 27 at 2; Avondale Tech. Servs., Inc., B-243330, July 18, 1991, 91-2 CPD ¶ 72 at 3.  To the extent that those prior decisions are inconsistent with our ruling here, we will no longer follow our prior decisions in this regard. (Champion Business Services, Inc., B-290556, June 25, 2002)
