Former presidential candidate Tan Cheng Bock's legal challenge will be heard in the last week of June.

Tan's affidavit to the High Court was to question the timing of changes to the elected presidency.

The Attorney-General's Chambers (AGC) is represented by Deputy Attorney-General Hri Kumar Nair, while Dr Tan is represented by Senior Counsel Chelva Retnam Rajah, of Tan Rajah & Cheah.

The timing of the hearing was addressed at a pre-trial conference in the High Court on Monday morning, May 22.

It is most likely a one-day hearing.

Tan's affidavit to the High Court was formally accepted on May 8.

The court challenge makes the AGC the defendant. It is to make the AGC say why the count of five presidential terms starts with former president Wee Kim Wee instead of his successor Ong Teng Cheong, causing a reserved election to be triggered.

Last November, Parliament passed changes to the Constitution to update the elected presidency.

The Presidential Elections Act was passed by Parliament in January 2017, several months before the election is due to be held by September 2017.

Tan had announced his intention to run for president in March last year, months before it was announced the next election would be reserved for Malay candidates.
