Each courtroom entry in the High Court building in Canberra comprises an air and sound lock with two sets of double doors and sidelights. The architecture is designed to convey a strong suggestion of privacy and hesitation before entering the solemnity, protocol and ceremony expected in courtrooms. The design theme across the courtroom doors is that of a grid formed by heraldic shields. The repetition and constant form of the shield imparts a sense of impartiality and universality as represented in the High Court. The shields represent the protection provided by the rule of law to the people. The forms and divisions within each shield are based on the combinations and variations found in the tradition of heraldry – here conveying the notion of Constitutional law as unfolding and capable of change as times change. The non-heraldic ribbon image unites the individual emblems, and represents the tapes used to bind legal documents, as well as the tabs used on legal dress – symbolising the qulity of binding, unifying and the flexibility of adjustment.
