In Martin v Lowry  11TC297 the individual bought a very large quantity of linen with the intention of reselling it at a profit. In the course of this activity he set up a large and skilled organisation for disposing of the linen in smaller quantities including the establishment of a sales office; the employment of staff and an expert in linen; and an extensive advertising campaign. This sales organisation was an important factor in the Commissioners’ decision that he was trading, a view with which the courts agreed.
The absence of the normal business systems and structures that would be expected of a trader dealing in the particular asset may be a pointer against trading.
