e) Mr. Gerald Kyei who is stationed in Accra was sent out for one month by his employers to attend to some business of the company in Tamale. In his absence, his wife Mrs. Kyei collected a variety of items from the 'Top Notch Collections Shopping Mall' (TNCSM) worth five hundred Ghana cedis (GH500.00) on credit and pledged that the husband will pay on his return. Upon Mr. Kyei's return he refused to pay (TNCSM) with the excuse that he is not liable. What is the legal basis for the wife's claim and what arguments must Mr Kyei advance to convince a court that he is indeed not liable?
