There’s almost a Lewis Carroll-like quality to the following passage in the Federal Register, (54 FR 52307-8, for those keeping score at home), in which the Office of Management and Budget published its interim rule for complying with the Byrd amendment, which barred government contractors and grantees from using federal funds to lobby (it became effective Dec. 23, 1989):

Costs made specifically unallowable by the requirements in the guidance are not made allowable under any of the provisions of these Circulars. Conversely, costs that are specifically unallowable under the provisions of these Circulars are not made allowable under the requirements in the guidance. Costs made specifically unallowable by the requirements in the OMB guidance will not be made allowable under any of the provisions of the FAR. Conversely, costs that are specifically unallowable under the provisions of the FAR are not made allowable under the requirements in the OMB guidance.

I’ll be posting the next part of the SF-LLL timeline soon.
