Late to the party here
This all goes back to "The Contract with America" (cue Newt G).
That bill contained the following provision (this is from the wikipedia on the Congressional Review Act):
"The law empowers Congress to review, by means of an expedited legislative process, new federal regulations issued by government agencies and, by passage of a joint resolution, to overrule a regulation. Once a rule is thus repealed, the CRA also prohibits the reissuing of the rule in substantially the same form or the issuing of a new rule that is substantially the same, "unless the reissued or new rule is specifically authorized by a law enacted after the date of the joint resolution disapproving the original rule" (5 U.S. Code § 801(b)(2))."
So in 1996 congress basically codified the idea of reviewing/overruling anything they had passed previously, but also prohibiting any new bill to supersede their new bill.
In other words, "I don't like this rule, so I'm going to change it. But no one after me can change my new rule".

Next on the chopping block - Net Neutrality.
This could also go in politics, but since that's not a default headcycle I guess technology is the best place for it.
I can believe they voted for this, but this thinking is freaking medieval.
edit - forgot some words
