Libby is a rich widow. She has a son, Jerry, and as he is her only family member, Libby has put all her effort and wealth into nurturing him. Jerry just graduated from university and has a strong desire to be independent. He started his own fashion design business and has entered into a contract with a company for the supply of sophisticated software tools that facilitate 4D designs and AR fittings for customers. He has paid $70,000 for the software. However, upon delivery, he discovered that the software is unable to perform the specified functions. He got upset and rejected the software. Jerry wants to claim back the HK$70,000.00.

A year ago, Libby invested the sum of HK$1,000 million in a medical project, which included the purchase of patent rights over a piece of newly invented equipment ('the equipment'). Due to an oversight by her legal adviser, the project only acquired restrictive rights over the patent and extra payment is required every time the equipment is used, thus increasing the expenses under the project by HK$70 million. Libby was very angry and wants to claim compensation from her legal adviser for the sum of HK$70 million.

Required:

Identify the court or tribunal where both Jerry and Libby should commence proceedings and describe in detail the functions of the court or tribunal that you have identified.
