Harry and Bill ran a restaurant as a partnership business. Harry suggested to Bill several times that the partnership business would grow if it had a licence for staging live music shows by performing artists. Bill was totally opposed to it saying that it would change the character of the restaurant, increase overheads and drive away regular patrons. Nevertheless, without telling Bill, Harry asked Goodricks, an attorney, to apply for and obtain a licence. Goodricks did so and submitted his claim for R5,000 for his professional services. Bill refuses to authorise payment saying that the partnership never authorised Harry to instruct an attorney for such a licence.Required:In the context of the above facts, advise Bill if the partnership is bound to pay Goodricks.
