Addressing a meeting of HJC workers here, Bishnoi said there was no question of him attending the rally when he had not been invited.
He said his party did not breach the coalition 'dharma' and alleged that BJP state leaders have been making irresponsible statements about the alliance after the Lok Sabha elections.
He said the ball is now in BJP's court and added that no compromise is possible on "self respect".
"My party is prepared to contest all 90 seats in the state," Bishnoi said, adding that the party will take a final decision about the continuation of alliance with BJP on August 19.
The HJC leader alleged that Hooda discriminated against Ambala in development and no big project was established here during the last decade.
