Article 98 also provides that the remuneration and other terms of office of Supreme Court judges may not be altered to their disadvantage following their appointment. Article 99 restricts parliamentary debate on the conduct of a Supreme Court judge unless on a substantive motion supported by at least a quarter of all MPs. However, it has been argued by some commentators that Singapore falls short where some aspects of judicial independence are concerned. For instance, Supreme Court judges above the age of 65 may be reappointed on a term basis. It has been suggested that this may result in "the unsavoury possibility of judges being 'beholden' to the executive". This point was also raised by Jeyaretnam in Parliament in 1986 with respect to the then Chief Justice Wee Chong Jin. However, an academic has pointed out that removing entirely the system of extensions may not serve the larger interest at the end of the day if excellent judges have to retire due to the mandatory requirement. Judges of the Subordinate Courts do not enjoy the security of tenure enjoyed by the Supreme Court judges. As officers of the Singapore Legal Service, it is said that there is a risk of executive interference because judges may be removed from their judicial positions or transferred to lower-ranking positions elsewhere within the Legal Service by the Legal Service Commission (LSC). In 1984, the Senior District Judge Michael Khoo acquitted Opposition Member of Parliament J.B. Jeyaratnam of all but one minor charge in a case involving cheques for the Workers' Party of Singapore which had allegedly been fraudulently handled. The acquittal was overturned on appeal to the High Court, and a retrial ordered. However, before the retrial took place, Khoo was transferred from his position on the Bench to the Attorney-General's Chambers to take up the post of deputy public prosecutor. This was considered to be a demotion. In 1986, Jeyaratnam claimed in Parliament that the transfer had been made because Khoo had ruled in his favour in the 1984 case. However, a commission of inquiry formed to look into the circumstances surrounding the transfer found no evidence of this. For making the allegation, Jeyaratnam was referred to Parliament's Committee of Privileges for abusing parliamentary privilege. While the Committee was considering the matter, Jeyaretnam wrote five newsletters about the Committee's proceedings and sent them to residents of his constituency. On 9 October 1986, the Leader of the House made a written complaint regarding the newsletters' contents to the Speaker of Parliament, which the Committee also considered. On 27 January 1987 Parliament accepted the Committee's reports on the complaints and found Jeyaretnam guilty of abusing the privileges of Parliament by alleging executive interference in the judiciary, and of contempt of the Committee and Parliament by publishing the newsletters.
