Later, the ECP adjourned the hearing until Oct 26.
Addressing the media, PTI's Babar Awan said the ECP has issued a non-bailable warrant in a case where a bailable warrant has already been dismissed by the Islamabad High Court.
The five-member ECP, bench headed by Chief Election Commissioner (CEC) Justice (retd) Sardar Raza Khan, was hearing a petition filed by the PTI dissident - Akbar S. Babar - when it issued "non-bailable warrants" for Khan. Following the submission of the apology, the case should have been decided, he further said.
The PTI leader had initially challenged the maintainability of the contempt petition and raised objections over the ECP's jurisdiction to initiate contempt proceedings against him.
Party spokesperson Naeem ul Haque echoed similar sentiments and expressed resentment over the regulatory body's orders.
However, Khan in a TV interview later said that his counsel had tendered an apology in his personal capacity and that he had not apologised.
Hearing his arguments, the bench had reserved its verdict in the case.
In a written response that accompanied the documents, Imran said that he had mentioned the transfer of the money from his account to Jemima's in financial documents submitted before the Election Commission of Pakistan in 2003.
In August, the ECP had issued a second show-cause notice to Khan after he failed to reply to an earlier notice regarding the contempt of court proceedings against him.
On September 14, the ECP had issued bailable warrants against Imran to ensure his presence in the case, besides directing him to submit a surety bond of Rs100,000 until September 25.
The ECP had issued the contempt notice to Khan on January 24 over his "scandalous remarks" about the commission.
