Triple Point Technology, Inc. v. PTT Public Company Limited case. 

The case involves a dispute between Triple Point Technology (a software company) and PTT Public Company (a Thai state-owned oil and gas company) regarding a software implementation contract.
The parties involved are:
1. Triple Point Technology, Inc.: A software company that was contracted to develop and implement a software system for PTT Public Company.
2. PTT Public Company Limited: A Thai state-owned oil and gas company that contracted Triple Point to develop and implement the software system.

The subject matter of the contract was agreed to be the development and implementation of a software system by Triple Point for PTT Public Companyaccording to the agreed-upon specifications. 
This was to include tasks such as software programming, customization, integration, testing, and support. PTT's obligation was to provide necessary cooperation, access to information, and any other requirements specified in the contract to facilitate the successful completion of the project.
The key legal question in the Triple Point Technology, Inc. v. PTT Public Company Limited case was the interpretation and application of the contract's liquidated damages clause.
Triple Point filed the action against PTT Public Company. Triple Point claimed that PTT owed it additional fees for work performed and sought to recover those fees. 

On the other hand, PTT counterclaimed, arguing that Triple Point was liable for liquidated damages due to project delays and failure to meet contractual milestones.
