How often do proposed private bills tend to become law?

Proposed private bills tend to become law rarely because of several factors, particularly time constraints and the specific nature of these bills. Private bills are typically introduced to benefit a particular individual, group, or locality rather than the general public, which means they often require extensive discussion and scrutiny to address the unique circumstances they pertain to. This scrutiny can lead to delays in the legislative process, and given that the parliamentary timetable is often packed with more pressing public matters, private bills may not receive the attention necessary to pass.

Additionally, private bills must undergo a particular process that includes petitions, committee reviews, and opportunities for objections, all of which can further complicate and prolong their passage. Consequently, the infrequent success of private bills reflects the combination of their specialized nature and the limitations of the legislative calendar.
