New Delhi, April 28 -- Aam Aadmi Party chief Arvind Kejriwal has written to Delhi High Court Justice Swarana Kanta Sharma, saying he will not appear in the excise case personally or through a lawyer before her, the party said on Monday. Pointing to a "grave miscarriage of justice", Kejriwal, in a four-page letter, said he has "serious and unreconciled" concerns regarding the matter. "I have decided that I shall not participate in the further proceedings in this matter, either in person or through counsel. I do not take this step lightly," Kejriwal added. In his letter, Kejriwal further said that "justice must not only be done, but must also be seen to be done"."The principle that justice must not only be done, but must also be seen to be done, is among the most sacred assurances that a court gives to a citizen in a democracy," he said. The assurance cannot be dishonoured by asking the citizen to ignore what "anyone can plainly see" in a case like this, he added in the letter. The letter also invoked the principles of Satyagraha and the teachings of Mahatma Gandhi, with Kejriwal saying that his intent is "strengthening of judiciary and prevent its weakening".He added that he has given the authority an opportunity to consider and correct what he perceived to be a grave miscarriage of justice.His earlier plea seeking the recusal of Justice Sharma, which was rejected on April 20, was interpreted as a personal attack, the AAP chief claimed. "After the said judgment, I am left with the painful and inescapable impression that what I had urged as a lawful plea of apprehension was received and answered as a personal attack upon Your Ladyship and as an assault on the institution itself. "Those are not, with respect, answers to the case I had brought. They show me that my plea of apprehension has been judicially understood as a personal and institutional affront," he said in the letter. Reflecting on his personal experience during the proceedings, the former Delhi chief minister expressed concern over the broader implications of his case on public trust in the judiciary, while he said he maintains respect for the institution. "When I appeared before Your Ladyship to argue my case, the question in my heart was simple: Will I get justice? Today, with the deepest respect, I must say that the same question has become graver and deeper in my conscience," he said. Addressing potential criticism, Kejriwal clarified that his remarks should not be interpreted as opposition to the judiciary. "As I write this, I am also cognisant of the fact that some might portray me as someone 'against' the judiciary. But how can that ever be the case when I have personally received relief from the judiciary, including orders of bail and the present discharge?"Today, I walk free because of the judiciary. Let there exist no figment of imagination that my present stand is against the institution," he said....
