Issue estoppel applies when parties or their privies are prevented in a subsequent suit from relitigating an issue which had earlier on been adjudicated upon by a court of competent jurisdiction and which same issue comes incidentally in question in any subsequent proceedings. In other words issue estoppel applies to preclude a party from contending the contrary or opposite of any specific point which having once been distinctly put in issue has with certainty and solemnity been determined against him.
