Court halts assembly sittings
At an emergency assembly meeting held under a tree in a car park next to the state secretariat, the Pakatan representatives passed motions to support Mohd Nizar Jamaluddin as the menteri besar as well as to dissolve the state assembly.
Meanwhile at the Ipoh High Court, a new twist developed when judge Ridwan Ibrahim told speaker V Sivakumar's lawyers that they had no legal standing to represent the speaker, who should be represented by the state legal advisor.
See below as developments unfolded.
4.56pm: Justice Ridwan has ruled in favour of Zambry by restraining the Perak speaker from convening state assembly sittings, according to Zambry's lawyers.

Speaker Sivakumar's lawyer Leong Cheok Keng and M Kula Segaran submit a letter to the judge stating that Sivakumar had no prior knowledge that the state legal advisor would be representing him.
The speaker told the judge that the decision to bar his lawyers from representing him this morning was wrong.
"I had no communication from the state legal advisor that he would be acting on my behalf," he said in the letter.
11.55am: Those who had lashed out at police personnel when Pakatan Rakyat state representatives were prevented from entering the state secretariat building this morning will be tracked down.
According to Bernama, Ipoh police chief Azisman Alias said more than 200 people had gathered outside the building but there were no untoward incidents.
However, he said several individuals had uttered harsh words against the police, and they would be tracked down from the photographs and videos taken of the incident.
Azisman said the police would also seek the help of the media to publish or broadcast the images of these individuals who attempted to prevent the police from exercising their duty.

10.35am: A new twist at the Ipoh High Court. Speaker Sivakumar's lawyer Tommy Thomas held a press conference to say that the judge had ruled that private lawyers have no legal standing to represent the speaker.
Thomas said that according to judge Ridwan Ibrahim, only the state legal advisor can act for the speaker since he (the speaker) is part of the state government.
With this ruling, Thomas said that they would be taking instructions from Sivakumar on the next course of action.
Thomas also said that their arguments that it would be a conflict for the state advisor to represent the speaker was dismissed by the judge.
