Match Referee Sunil A Chaturvedi said Harbhajan has been fined for showing 2.13 level one misconduct (showing dissent to the umpire's decision) during the five-day knockout stage Ranji Trophy tie at Keenan Stadium.
The out-of-favour India off-spinner indulged in an argument with umpire CK Nandan (Karnataka) after the latter turned down his appeal for catch while bowling against Sunny Gupta in the 108.4 over.
Harbhajan was summoned by the match referee and after having a discussion for over 15 minutes, Chaturvedi slapped the fine on him.
Earlier, Harbhajan had bagged a wicket of Jharkhand opener Ramee Nemat, who had completed his maiden ton off 229 balls studded with ten boundaries.
