The Delhi High Court has junked - for a third time - a plea seeking the removal of Arvind Kejriwal as Chief Minister after his arrest last month over corruption allegations.

In a significant observation, a bench led by acting Chief Justice Manmohan said "Let democracy take its own course".

The court - a different bench of which will rule later today on Mr Kejriwal's plea for interim relief in this matter - also refused to counsel Delhi Lieutenant Governor VK Saxena on forcing the Aam Aadmi Party leader to relinquish his post. "He (Mr Saxena) doesn't need our guidance. We are nobody to advise him. He will do whatever he has to, in accordance with the law," the High Court said.

"Why this urgency? I am not talking about politics... am talking about law," senior advocate Abhishek Manu Singhvi said, arguing the arrest was meant to "demolish AAP before the first vote is cast".

Kejriwal is the AAP's biggest public face and crowd-puller.

After hearing Mr Singhvi and the counter by the arresting agency (the Enforcement Directorate), the High Court reserved its verdict for this afternoon.

Kejriwal is currently in Delhi's Tihar Jail; he has been remanded to judicial custody till April 15.

The court was hearing a public interest litigation by the Hindu Sena, which sought direction to the Lieutenant Governor to direct Mr Kejriwal to resign. The petitioner was told to prioritise national interest over "personal issues" and, if it wanted to persist, to "raise this issue before another forum".

Last week the acting Chief Justice said the removal of a sitting Chief Minister is outside the scope of judicial interference. "It is for the other wings of the government to examine, in accordance with the law, this issue," the court said. And for the plea before that, a bench led by then Chief Justice Rajendra Menon made a firm statement, noting "prosecution is going on... he may be acquitted".

Arguing for interim relief Wednesday, Kejriwal's lawyer questioned the timing of the arrests.
