Precedence among amendments that are directed to the same text:
The first of these principles is axiomatic. A second degree amendment is an amendment to a first degree amendment, and it must be offered while the first degree amendment is pending—that is, after the first degree amendment has been offered but before the Collective has disposed of it. The Collective also acts on an amendment to a first degree amendment before it acts on the first degree amendment itself. So this principle conforms to Collective practice under both meanings of precedence.
