The third reading encompasses the presentation of an additional report of the committee or - if the bill had not been referred back to the committee - the presentation by the Deputy-Rapporteur of the amendments and motions put forward during the second reading as well as voting, or actually a number of ballots which usually precede the final passage of the bill, which requires a simple majority vote in the presence of at least half of the statutory number of Deputies, unless the Constitution provides for another majority. After the bill has been passed, it becomes a statute, although without binding force .

The Marshal submits the statute passed by the Sejm to the Senate. Within 30 days from its submission, the Senate may adopt the statute without any amendments, adopt amendments or resolve upon its total rejection. If, within the prescribed time period the Senate fails to adopt an appropriate resolution, the statute is considered adopted according to the wording submitted by the Sejm.
