California Assembly Rule 77.2 Substantially Amended Bills 77.2. If the analysis of an amendment adopted on the floor discloses that the amendment makes a substantial substantive change to a bill as passed by the last committee of reference, the bill, as amended, may be referred by the Speaker to the appropriate committee. A bill that was previously reported from a policy or fiscal committee of reference in compliance with Joint Rule 61 is not subject to the deadlines in Joint Rule 61 if the bill is subsequently referred to a policy or fiscal committee pursuant to this rule. If the digest to an Assembly Bill that has been returned to the Assembly by the Senate for concurrence in Senate amendments discloses that the Senate has made a substantial substantive change in the bill as first passed by the Assembly, the bill may be referred by the Speaker to the appropriate committee.
