The change takes effect the day this law passed
What the document says“The amendment made by this section shall take effect on the date of enactment of this Act.”
The section provides that its amendment takes effect on the date of enactment.
What the document actually says“The amendment made by this section shall take effect on the date of enactment of this Act.”
That sentence, in plain words
The change starts on the day this law passed. Nothing before that is touched.
What this is about
The old rule still holds up to then. The date is fixed in the law. There is no delay built in.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
