3. Faced with this array of claimants, Riverhall commenced interpleader proceedings in the Supreme Court of Western Australia against In Residence, MPP, Amberwood and Mr. Sweeney. In accordance with the requirements of the Supreme Court Rules, Rules of the Supreme Court (W.A.), O.17, rr. 1 and 2, the application for relief by way of interpleader was supported by affidavit evidence that Riverhall: (a) claimed no interest in the amount owing other than for charges and costs; (b) did not collude with any of the claimants to the benefit of the amount due; and (c) was willing to dispose of the amount of the debt in such manner as the Supreme Court or a judge thereof might direct. On 30 June 1981, it was ordered by a judge in Chambers that Riverhall pay the $198,195 into court and that the defendants to the interpleader proceedings (i.e. the four claimants) have liberty to apply for the purpose of having the moneys placed on interest bearing deposit pending the determination of the proceedings. Subsequently, and before the entitlement of any of the claimants had been determined, it was ordered by a judge in Chambers that the moneys paid into court be paid out to the solicitors for In Residence for investment with the Town and Country Building Society ("the Building Society"), that the investment be made in the names of the present appellants ("the appellants") "and that such moneys be held on trust by them pending the determination of these proceedings". The appellants were solicitors acting for one or other of the claimants. On 30 April 1982, the $198,195 was deposited with the Building Society on "a redeemable interest bearing investment deposit" in the names of the three appellants. Thereafter, and pending resolution of the issues between the claimants, interest accrued on the moneys held by the Building Society. During the financial years ended 30 June 1983 and 30 June 1984 ("the tax years"), interest in the amount of $39,883.30 and $30,665.90 respectively was derived.
