There was a petition to the Rulers protesting the appointment of the new Chief Justice, mainly on the grounds that he was an UMNO lawyer.
That petition was ignored and the new CJ has been appointed.
Under the "new broom sweeps clean" syndrome, the CJ claims that he believes that there were two judges who were corrupt as detailed in this malaysiakini article Kit Siang to Zaki: Report 'retired corrupt judges' to ACA as this will enable the name of the Judiciary to be restored a little.
To allay fears that UMNO cases would be given special favours, the CJ wants to avoid hearing such cases as reported in this other article CJ: I won't hear Umno cases.
I think this approach is flawed as time alone will not erase the UMNO connection. If he has the capacity to judge without fear or favour, he should just treat UMNO cases like any other. That will hasten the day when the public perception of a flawed and tainted Judiciary will change for the better.
As for his own corruption experience, now that he has declared it, he should make the necessary police reports and bring the culprits to book.
