For ten years, Sammy owned a garage in Karibib. He then sold the garage to Fred for N$ 200 000. The contract provided that for a period of 5 years, Sammy would not be allowed to open a similar business in Karibib. Two years after Fred had purchased the garage, Sammys boredom gained the upper hand. He started to set up a new garage in the town of Karibib and advertised that he would shortly be back in business again. May Sammy do this? Discuss the applicable legal concept and consequences thereof.
