Clause 17 of the First Schedule to the Workers' Compensation Act
1912-1941 (W.A.) provides : - '' Where any weekly payment has been
continued for not less than six months, the liability therefor may, on
application by or on behalf of the employer or worker, be redeemed
by the payment of a lump sum." The lump sum in default of agree-
ment was to be settled by the Local Court, but clause 18 provided
that, when the court ordered redemption, the lump sum was to be
assessed upon a calculation by a Government actuary of the present
value of the balance of compensation still payable or likely to be
payable under the Act by way of weekly payments. No deduction
of any nature or kind could be made by the court from such actuarial
valuation for any reason whatever. But the Workers' Compensation
Act Amendment Act 1944 (1944 No. 42), assented to on 11th
January 1945, provided (s. 4 (g)) that, when the court ordered
redemption in case of permanent incapacity whether total or partial,
the lump sum should be the sum ascertained by deducting the total
amount received by the worker as weekly payments from the maxi-
mum sum of £750, The appellant met with an accident in June 1943
which involved permanent incapacity. He received weekly pay-
ments pursuant to the Act for more than six months, when he applied
for redemption. The application was lodged on 15th December 1944,
the amending Act was assented to on 11th January 1945, the applica-
tion for redemption was heard on Ist March 1945. The appellant
contended that he was entitled to redemption under the provision
of the Act passed on 11th January 1945, but the Local Court rejected
his contention, and its decision was affirmed on appeal to the Supreme
