There are, of course, safeguards against error in judicial decision and what
may flow from it. Decisions of courts are always - or should always be - subject
to appeal. Ideally in all cases - and in practice in most of them - the findings and
orders of a court at first instance are reviewable on appeal. Appeals now
ordinarily involve at least one review of factual findings: see, eg, the Supreme
Court Act 1970, s75A (appeal to the Court of Appeal by way of rehearing). On
such an appeal the court may, subject to recognition of the advantages of the trial
judge: Abalos v Australian Postal Commission (1990) 171 CLR 167; Louth v
Diprose (1992) 175 CLR 621; reconsider and redetermine the findings of fact
made. The present problem is, of course, different. It concerns errors of fact
which cannot be or have not been corrected on appeal. In some circumstances,
decisions so made may be set aside, eg, in some cases of mutual mistake, fraud
or the like: see generally McDonald v McDonald (1965) 113 CLR 529; Halsbury,
Laws of England (4th ed) Vol 26, pars 557, 560. But special cases apart, the
findings and orders of courts remain effective notwithstanding that it
subsequently appears that errors of fact have been made. In certain statutes,
provision has been made for a more extensive review of judicial decisions. Thus,
in the Landlord and Tenant (Amendment) Act 1948, provision was made for a
review de novo of orders made in respect of the possession of premises: see 71;
Burling v Chas Steele and Co Pty Ltd (1948) 76 CLR 485; Hilliger v Hilliger 52
SR (NSW) 105. Similar review was possible under the Workers Compensation
