Always two readings
Bills require two readings and are considered on the basis of a committee report, which may recommend significant changes to the government proposal. A committee may also recommend that a bill or parts of it be rejected.
In the first reading Parliament decides on the content of a bill. Following a general debate, it looks at a bill section by section. During this stage changes are often proposed to the recommendations in the committee report.
The second reading can begin no earlier than the third day after the first reading and is based on the text approved in the first reading. At this time a bill is either approved or rejected; the content can no longer be changed.
