Can regular inquiry be held after domestic inquiry was held previously

An employee suspended from job. Domestic Inquiry was conducted against an employee by Retd. High Court Judge. After only 3 dates and without evidences/witnesses, the Inquiry officer conclusion was: "I conclude that prima facie case is made out against employee under charge no. 1 to 5. In view of the above conclusions, the competent authority may, in its discretion, order an in depth regular Inquiry against the employee." The suspension is STAYED by District and Session Court under Educational Tribunal. Now, employer gave the letter of holding Regular Inquiry against the employee again by another Retd. High Court Judge. Please suggest, what employee can do now?
