Meanwhile, Sid is also a private contractor with five workers. Sid has contracted with Riku to renovate his kitchen as preparation for Riku's engagement party in February 2021. Riku paid Sid RM5000.00 as a deposit, and they both agreed that the work must be done within two weeks and to be completed before Christmas 2020. Sid promised Riku that he would start the renovation on 1st December 2020. However, two days before December 2020, Sid and two of his workers tested positive for COVID-19 and were hospitalised for treatment. Sid informed Riku that he could not start the work within the time agreed. There will also be delays in completing the project as the other three workers were self- quarantined. Riku was so furious as he plans to organise a private Christmas party with his family and close friends to show them his newly renovated kitchen. Invitations have been sent, and Riku is embarrassed to cancel the event. Consequently, Riku terminated the contract and wanted to sue Sid. With reference to the Contracts Act 1950 and relevant legal authorities, advise Sid on the legal implication(s) of the above situations against: (a) Kai (30 Marks) (b) Leo (30 Marks) Riku (30 Marks) I IF
