been any attempt in the company's accounts to treat the expenditure incurred in establishing it, or in building it up, as a revenue expen- diture. No debit was made to revenue account until a spare part was issued and went into use. No part of the £25,361 or the £7,702 is or has been reflected in profit and loss. For these reasons I think that the loss is one of capital or at all events is of a capital nature and cannot be deducted under S. 51.
The commissioner relied upon further answers to the company's use of S. 51 in support of its claim to the deduction. But, as I accept the commissioner's view that the loss is an affair of capital, it is unnecessary to discuss them.
On behalf of the company, however, some reliance was placed on S. 59. Section 59 could not apply unless the spares or the stores, as the case may be, were brought within S. 54. Even if they could be treated as "plant" within that provision, which I doubt, I do not think that it could be said that that thay had been used during the year for the purpose of producing assessable income or had been installed ready for use for that purpose. These, or one of them, form essential conditions of the application of S. 54.
In my opinion the claim to deduct the loss fails. The appeal will be dismissed with costs.
From this decision Guinea Airways Ltd. appealed to the Full Court.
K. L. Ward K.C. (with him J. J. Redman), for the appellant. J. W. Nelligan K.C. (with him C. A. Sandery), for the respondent.
Cur. adv. vult. The following written judgments were delivered:
LATHAM C.J. This is an appeal from an order of Dixon J. dismissing an appeal from an assessment of Guinea Airways Limited to income tax. The question which arises relates to a deduction claimed by the company under S. 51 (1) of the Income Tax Assess- ment Act 1936-1942. Section 51 (1) is in the following terms
" All losses and outgoings to the extent to which they are incurred in gaining or producing the assessable income, or are necessarily incurred in carrying on a business for the purpose of gaining or producing such income, shall be allowable deductions except to the extent to which they are losses or outgoings of capital, or of a capital, private or domestic nature, or are incurred in relation to the gaining or production of exempt income."
