Chew is a horse racing fan and tells Lim, the manager of his construction company,

to attend an auction and bid on his behalf for the horse, Hannibal. He told him to

spend 'not a cent more than $100,000' on the horse. Lim bids $100,000 but with the

auctioneer's commission and GST he receives an invoice for $120,000. Lim is

himself very knowledgeable about horse breeding and he thinks that Hannibal could

be sold for $150,000. In anticipation of Chew's rejection of the horse, Lim starts

negotiations with a buyer willing to pay him $150,000 for Hannibal.

Advise Lim as to his legal rights and duties and how he should deal with the matter.
