The adoption of this report occurs after the committee of the whole stage in the passage of a bill through the Senate. The committee reports to the Senate that it has considered the bill and has agreed to it with (or without) amendments. The adoption of the committee report is the stage at which the Senate determines whether to accept the bill as a prelude to the final vote, or to send it back for further consideration.
Amendments may be moved to the motion to adopt the report from the committee. Such amendments do not affect the text of the bill or bills, but typically propose the reference of related matters to committees, propose an order for the production of documents or express an opinion about the bill as it has emerged from the committee of the whole.
