His action has nothing to do with the company for the contract with him has been repealed due to the latter's failure to meet certain security standards, as stipulated by the contract.

The signed contract stipulates that a third party will examine the dogs' ability to uncover explosives at oil installations. The third party has tested the dogs after concealing explosives in some vehicles. But the dogs have failed to detect the explosives, prompting the company to end the contract.
