Technically isn't this already tabled.
The sponsor of a piece of legislation may at any time withdraw their sponsorship. In addition, when the sponsor is no longer a Senator, their sponsorship shall be revoked automatically. If no member of the Senate moves to assume sponsorship of the legislation within 48 hours, the legislation shall be tabled automatically.
What worries me about this whole business is that we continued to propose amendments, vote up and down etc. on a ghost bill, which serves of course to demonstrate why the people in charge need to actually control this aspect of the floor proceedings so that this kind of thing doesn’t happen.
Anyway, unambiguous language and all that, consider this bill tabled.
