The Delhi High Court on Wednesday imposed a cost of Rs 10,000 on Chief Minister Arvind Kejriwal after he failed to file a reply in a second Rs 10 crore defamation suit by Union Finance Minister Arun Jaitley over his former lawyer Ram Jethmalani using the word "crook".

The fine was imposed by Joint Registrar Pankaj Gupta after Kejriwal failed to file response on the plea, and granted further two more weeks to respond.

Jaitley, in the second civil defamation suit against Kejriwal, claimed the objectionable words caused him "permanent harm and disrepute".

This is a separate case from the ongoing Rs 10 crore Delhi and District Cricket Association (DDCA) defamation suit against Kejriwal and five other Aam Aadmi Party leaders that Jaitley filed in 2015.

On May 17, Jaitley and senior advocate Jethmalani clashed in the court with the Union Minister taking strong on objectionable word that Jethmalani used in his cross-examination.
