38. Thus a direction to leave Canberra for six hours would not be authorised. A direction to leave and not return to the entire suburb of Kingston would not be warranted. However, a direction to remain a specified but reasonable distance from Green Square or, indeed, the public places near Filthy's, may well have been. However, the essence of the offence is the contravention of the direction including any authorised condition. It is not being in an area that might have been specified but was not. It was accepted that the direction could not have included a direction to leave or not enter Filthy's. I make no comment on whether that concession was rightly made and accepted but no argument was addressed to it and I therefore do not express a view on whether licensed premises then open for business are or are not public places for the purposes of the CPP Act. The direction was confined to leaving "Green Square". It would be apparent to an observer, even without the maps tendered, that Green Square was the area bounded by the curtilage of the Cusack Centre and Green Square buildings facing the paved and lawn (or formerly lawn) areas in front of those buildings up to Eyre Street to the east and Jardine Street to the north. To go beyond the boundary between those streets and the paved edges of Green Square could not reasonably be regarded as doing anything other than leaving Green Square. To take the footpath travelling west along the southern side of Jardine Street would be leaving Green Square. Similarly, to have exited into Highgate Lane would have been leaving Green Square. It was, of course, open to the informant to direct the route of departure. To regard the direction as implicitly forbidding the directed person to go to any other destination is completely impermissible. It would render a person liable to criminal sanctions for breach of an indeterminate obligation. Nor should a person be exposed to criminal sanctions for breach of an obligation that might have been imposed but was not.
