NSF reserves the right to conduct pre-award reviews of applicants for Federal financial assistance from NSF in cases where the NSF has substantial reason to believe that a potential recipient who is not then a recipient of other NSF financial assistance under the same program or activity may engage in practices under that program or activity that would violate the Act. However, the results of any such review shall not constitute a basis for NSF refusal to grant financial assistance to the applicant under that program or activity unless the procedural requirements of the Act (42 U.S.C. 6104 ) and §§ 617.12 and 617.13 of this part have been followed.
