High Court, in planning and development judicial review proceedings, quashes planning board's decisions deeming a change of use at a property from a nursing home to a residential drug rehabilitation facility to be 'development' and not 'exempted development', on the grounds that the legislative scheme does not provide the board with powers to make such determinations on foot of statutory referrals where the avenue of judicial review is the appropriate forum upon which to seek relief; and thus the board acted ultra vires its powers in making the determinations now impugned.
