Coca-Cola's argument was that "real danger that the bottle used by [A.G. Barr] for containing Kolabar will be mistaken by the public for [Coca-Cola].", while A.G. Barr's argument was "the position of Coca-Cola in the soft drinks industry in Scotland is insignificant in comparison with that of [A.G. Barr]". Lord Walker refused the interim interdict, as a large part of their business could've been disturbed, additionally because Coca-Cola made no sales in the country at that point.[25][26]
