This incident was covered extensively in JBJ’s book, and also in the International Bar Association’s report on human rights and the law in Singapore:

“Former Workers’ Party leader and Senior District Judge Joshua Benjamin (J B) Jeyaretnam was elected to parliament in a by-election in 1981, breaking the PAP’s 16-year parliamentary monopoly. He was re-elected in 1984. However, in 1986 he was accused of the misuse of party funds. He was acquitted at first instance (by Justice Michael Khoo, considered further below), but the appeal was upheld and a retrial heard by a District court. Mr Jeyaretnam applied for the retrial to be heard before the High Court, which would have allowed an appeal to be taken to the Privy Council, but this was rejected and he was convicted at retrial. As a result of his conviction, he was expelled from Parliament and disbarred from the Singapore Law Society. Mr Jeyaretnam was able to appeal only his disbarment to the Privy Council in London, which strongly criticised the original conviction and concluded in obiter dicta that Mr Jeyaretnam had not committed the offences for which he had been found guilty.

[...]

Shortly after this decision, appeals to the Privy Council were abolished by Singapore. While not unusual in itself, this sudden reversal of previously strong support for the final appeal system casts doubt on the intentions behind the abolition. Further, Goh Chok Tong criticised the Privy Council’s
decision in the Jeyaretnam appeal, alleging that it had exceeded its role and was ‘playing politics’.”
