The law of parliamentary privilege in New South Wales is the sum of certain immunities, rights, and powers enjoyed by the individual Houses of the Parliament of New South Wales, together with their members and committees, as constituent parts of the Legislature. The law is complex. It is liberally interspersed with uncertainty and ambiguity. It is also distinctly different from the law of privilege in other Australian jurisdictions, including the Commonwealth, and also from overseas jurisdictions. It is singular in the degree to which it relies on the common law, without recourse to statutory expression or to the historical privileges of the Houses of Parliament in the United Kingdom. Nevertheless, in some respects, the Parliament of New South Wales has been remarkably successful through the courts, and through its own procedures, in asserting the powers and rights of members under the banner of parliamentary privilege, notably in relation to orders for the production of State papers.
