Pakistan's Supreme Court has rejected a response from Imran Khan, the cricketer turned politician, who is accused of contempt of court.
The case against him was adjourned for three weeks on Friday, after he appeared before a three-member bench headed by Chief Justice Iftikhar Muhammad Chaudhry.
In July, Khan claimed that the general election in May which he contested in had been rigged.
The court said his response was "insufficient".
Khan is accused of trying to incite hatred against the court with the remarks made to a journalist.
Denying the claims in court, Khan was reported to have said: "The restoration of the judiciary had been on my agenda. I had also spent eight days in jail for that."
Khan contested in the election to become prime minister with his Movement for Justice party, or Pakistan Tehreek-Insaf (PTI).
The court has now demanded that Khan's lawyer Hamid Khan, who flew in from the US to attend the hearing, submit a detailed response on August 28.
