Can we run any test case from project tear down?

Thanks Rao for your response but you can share some ideas to achieve the below problem,

As part of my project I need to send the email to the team so I used email sender code and appended in the project tear down which is not good program practice so I thought to save it as common script and plan to invoke when ever required..

Hence I decided to call from tear down but unfortunately I couldn't done the without test runner so can you help me on this issue??
