These included the plan to set up checkpoints at every gate of the Chaeng Wattana government complex, with only the main gate near the administrative court open.
On Monday, Supreme Court officials advised the media to submit in advance their car licence numbers to avoid any difficulty that the security measures could case.
A police source also said that security checkpoints would be set up in various areas across the country starting on Wednesday. Any suspicious movement would be blocked and the people involved could be detained.
