The pro-government United Front for Democracy against Dictatorship (UDD) has cancelled a mass gathering planned for today, citing the need to assess the political situation.
The UDD previously intended to hold a rally today ahead of the Constitutional Court's ruling on the status of caretaker Prime Minister Yingluck Shinawatra.
The ruling follows the Supreme Administrative Court's judgement last month that Ms Yingluck's removal of then National Security Council chief Thawil Pliensri three years ago was unlawful.
UDD spokesman Thanawut Wichaidith said yesterday the group needs to gauge political developments.
The cancellation of the rally does not mean the UDD will scale back its activities, he said. The group will mobilise the gathering only when there is a major political development, he added.
The UDD's move came shortly after the Constitutional Court announced it will decide next week whether to grant another 15-day extension for caretaker Prime Minister Yingluck Shinawatra to defend her case over Mr Thawil's transfer.
The UDD's planned rally today was seen as a warm-up for the next major demonstration ahead of the Constitutional Court's ruling on the Thawil case.
Both the UDD and the anti-government People's Democratic Reform Committee (PDRC) have tied their next move to the court's ruling date against Ms Yingluck and the cabinet ministers.
The UDD said they will hold a major rally one day ahead of the court's verdict day, while the PDRC told its supporters to appear in the streets on the verdict day.
Both camps expected the court to hand down the ruling by the end of this month.
However, Ms Yingluck's lawyer yesterday requested the court extend the day of her defence by 15 days.
Chaovana Trimas, the court secretariat, said Ms Yingluck's lawyer had submitted the request to the court yesterday, asking the court to allow more time for the caretaker premier to prepare her defence.
The court earlier ordered Ms Yingluck to defend herself today.
Mr Chaovana said the court will decide next Wednesday on whether to grant another 15-day extension for the caretaker prime minister.
"Those who requested have exercised their rights which is a part of consideration process. But the court reserves the authority to grant the extension," Mr Chaovana said.
He reiterated the court always follows fair deliberation processes and hasn't discriminated with any cases.
The court has no political interests. It considers every case based on the law and without any political interference, he told a press conference, which was held to mark the 16th anniversary of the Constitutional Court yesterday.
Since its establishment, the court has received a total of 1,203 complaints, of which 667 cases were finalised, 496 cases were dropped, and 40 cases are being deliberated.
