Leo and Kenny are friends from University. Leo wanted to sell his car and asked Kenny if he knew of anyone who would be interested in purchasing his car. Kenny said he would be interested. They agree on a price of $17,000 to be electronically transferred to Leo. The next week Leo and Kenny meet to fill out the transfer of vehicle forms and Leo hands over the keys to Kenny. Leo informs Kenny he has yet to receive the $17,000. Kenny apologises and tells Leo he forgot but will electronically transfer the $17,000 to him when he gets home. Two weeks later and after 4 phone call reminders Leo has yet to receive any payment from Kenny. Leo tells his older brother Steven what has happened. Steven decides he should sue Kenny.

In your own words, explain whether Steven has the right to sue Kenny. Ensure you explain the relevant law in full before justifying your answer.
