help please

Your organization has recently been through an arbitration hearing with a former employee who was not selected for promotion. The employee believes that they were not selected because of their ethnicity. The situation was very embarrassing for the company and led many employees to view the internal hiring process as unfair. As a result, the CEO wants HR to eliminate any selection method that has the possibility of differentiating candidates based on race, age, disability, or religion (ie, cognitive ability tests, physical ability tosts, psychomotor tests, etc.). What would you tell the CEO in response to his request? Back up your logic and justify your position
