Yn sgil dyfarniad y llys, mae angen ailedrych yn awr at nifer o gwestiynau a godwyd ym mis Mai 2018 yn y protocol gweithredol ar gyfer yr ymchwiliad, sef:A ddylai unrhyw dystiolaeth lafar a roddir i’r ymchwilydd annibynnol gael ei chlywed yn breifat (paragraff 30 o’r protocol gweithredol);A ddylai’r ymchwilydd annibynnol gael y pŵer i wrthod caniatáu i’r hawlydd a theulu Mr Sargeant fynychu gwrandawiadau os bydd y ffaith eu bod yn bresennol yn achosi i dyst dynnu’n ôl er ei fod wedi cydsynio i roi tystiolaeth (paragraff 30 o’r protocol gweithredol);A ddylid gwrthod caniatáu i’r hawlydd a theulu Mr Sargeant ofyn cwestiynau i unrhyw dyst drwy eu cynrychiolydd cyfreithiol (paragraff 32 o’r protocol gweithredol).
As a result of the court’s judgement, a number of questions raised in May 2018 in the operational protocol for the investigation now need to be revisited. These are:Whether any oral evidence given to the independent investigator should be heard in private (paragraph 30 of the operational protocol);Whether to empower the independent investigator to refuse to permit the claimant and the family of Mr Sargeant to attend hearings if attendance will cause a witness to withdraw his or her consent to give evidence (paragraph 30 of the operational protocol);Whether to refuse to permit the claimant and the family of Mr Sargeant to ask questions of any witnesses through their legal representative (paragraph 32 of the operational protocol).
