The party also ruled out Yeddyurappa's resignation in the wake of the governor's action.
Taking stock of the crisis triggered by Bhardwaj's action, an emergency meeting of the party declared it would fight "legally and politically" against the governor's sanction which it described as "unconstitutional and politically-motivated".
BJP decided to call a statewide bandh tomorrow to protest the governor's action, BJP State unit president KS Eswarappa told reporters in Bangalore.
"There is no question of the chief minister resigning. We will fight out legally and politically", BJP general secretary Dharmendra Pradhan, also incharge of BJP affairs in Karnataka, said.
Pradhan was earlier rushed to the city by the BJP central leaders to guide the state unit in deciding the future course of action against the Governor.
Eshwrappa described Bhardwaj's decision as a "murder of democracy, a black order in the history of the state and done under the promptings by Congress and JD(S)".
"The governor is carrying on his political agenda through his office and trying to breathe life to Congress", he said.
He said Bhardwaj should tender an unconditional apology to the people of the state for his offensive remarks made against the government.
