A hybrid bill is a type of public bill which also contains elements normally characteristic of a private bill.
Such a bill will affect the public as a whole but will also contain elements that impact directly on particular individuals or local interests.
As a result it has to go through a longer parliamentary procedure than an ordinary public bill.
As well as being debated in both Houses in the usual way, individuals and local organisations directly affected by the bill are given the opportunity to put their case to special select committees of Members of Parliament or peers.
Examples of hybrid legislation include bills passed relating to the Channel Tunnel rail link and to the Crossrail project.
