The facts alleged in the statement of claim as giving the plaintiff the right to relief which the demurrer denied may be stated as follows. In June 1946 the plaintiff let the premises to the defendant on a weekly tenancy. The demised premises formed a portion, known as No. 159 Stanley Street, Brisbane, of the Atlas Hotel Building, that portion comprising the basement, ground floor and first floor of the building and a yard appurtenant thereto. The defendant went into possession of the demised premises, and in January 1948 he sublet portion of them to the Factor Trading Company. In February 1948 the defendant, without the knowledge or approval of the plaintiff, sublet the first floor of the premises to one James. On 13th April 1948 the plaintiff gave the defendant a notice to quit in respect of the whole of the premises in accordance with the National Security (Landlord and Tenant) Regulations upon two grounds, namely the commission of waste and the subletting to James: reg. 58 (5) (c) and (n). The defendant did not notify the plaintiff of the names and addresses of his sub-lessees as he was required to do by reg. 73 (2) (a). On 25th May 1948 the plaintiff commenced proceedings against the defendant to recover possession of the premises, under the provisions of the Summary Ejectment Act of 1867 Q., and on 17th June 1948 an order was made that a warrant of possession be issued to put the plaintiff in possession of the premises and that the warrant be executed on 15th July 1948. On that day a constable of police, at the premises, produced the warrant to the defendant and the defendant and the Factor Trading Company vacated the basement and ground floor of the building and the yard, but James continued in occupation of the first floor. The warrant was not executed against James because James had obtained an ex parte injunction restraining the plaintiff from entering into possession until 21st July 1948. On 19th July 1948 James gave notice of discontinuance of the action in which the injunction had been granted, and made an application under reg. 64 (b) for rescission of the order made on 17th June so far as it related to the portion of the premises occupied by him. Before this application was dealt with, the defendant filed an application under reg. 64 (b) for rescission of the order. On 13th August 1948 James' application was heard and refused. The plaintiff then applied orally for an extension of the time for the execution of the warrant and on 23rd August 1948 made the like application in writing. But on 27th August 1948 the defendant's application to rescind the order and warrant for possession was granted, a direction was given that notices be given to the Factor Trading Company and James under reg. 73 (2) and the proceedings were adjourned to 9th September 1948. On 1st September 1948 the National Security (Landlord and Tenant) Regulations ceased to have effect in Queensland pursuant to an order under reg. 7aa, subject of course to sub-reg. (3) of that regulation: Commonwealth Gazette No. 123 of 1948. On the same day The Landlord and Tenant Act of 1948 (No. 31 of 1948) Q. came into force. The plaintiff appealed from the order rescinding the order and warrant for possession and on 22nd November 1948 the Supreme Court allowed the appeal and remitted the matter to the Court of Petty Sessions to be dealt with: Bowles v. Anderson [1] . The defendant and James then gave notice of appeal to this Court but not until 4th March 1949. The appeal was abandoned, however, and on 15th June 1949 it was formally dismissed by this Court. On 4th July 1949 the application made by the plaintiff on 23rd August 1948, i.e., for the extension of the warrant, was heard by the magistrate, and an order was made that the warrant be executed within fourteen clear days from 4th July 1949. It was in fact executed on 15th July 1949, and the plaintiff then entered into possession of the whole of the premises. The plaintiff incurred legal expenses in connection with James' application to rescind the order, the defendant's application for the same purpose, the appeal to the Full Court, and the plaintiff's own application for extension of the time for execution of the warrant. The plaintiff also lost mesne profits or rental for the period of one year, i.e., from 15th July 1948 to 15th July 1949.
