the plaintiff of his appointment was an acceptance of his offer whi
was made legally binding on the determination of his salary. Th
was never a contract for service at a salary to be fixed. The con-
tract was not divisible, and the salary was an essential part of it
(Loftus v. Roberts (1) ). The reference in the letter to £1,000
annum meant for the term of five years, as is shown by the
liminary negotiations, which are admissible (Carey v. The Common-
wealth (2) ; Bond v. The Commonwealth (3) ). There is a prerogativi
right in the Crown to grant an office for a term of years (Chitty's
Prerogatives of the Crown (1820), p. 82), and it follows that th
must be a prerogative right to grant a fixed salary for
definite time also (Todd's Parliamentary Government in Englai
Ist ed. (1867), vol. 1, p. 375). The only ground on which
the salary might be altered is under sec. 37 of the des
Interpretation Act 1915. The word "determine," prima facie,
involves finality. If the contract is for a fixed period, there i
no power to redetermine the salary, for such a power is inci
dental to the power to dismiss (Hunkin v. Siebert (4)). Sec. 37.
only gives the right to determine the salary at the end of the period ;
it does not give power to break an existing contract. The section
was enacted only to rebut the common-law presumption that a
power once exercised is extinguished (Halsbury's Statutes of England,
vol. 18, p. 1003; Halsbury's Laws of England, 2nd ed., vol. 25, pp-
567, 568; Farwell, Treatise on Powers, 3rd ed. (1916), p. 306). The
Governor could have reserved power to make a further determination
as to the salary. Sec. 37 only applies if the occasion requires. The first:
exercise of the power to determine the salary created a right, and
the occasion did not require that that right should be defeated
(Nelson v. James Nelson & Sons Ltd. (5)). [Counsel also referred
