"There is a constitutional crisis in Karnataka in the wake of BJP MLAs supporting BSR Congress floated by former minister B Sreeramulu and Karnataka Janata Party led by former chief minister BS Yeddyurappa," Parameshwara told reporters outside the Raj Bhavan.
The delegation also appealed to the Governor not to give assent to the Cow Slaughter ban bill and also the Private Universities bill, he said.
Siddaramaiah said the Shettar government has no moral right to continue in office as it has lost majority.
Fourteen MLAs have been openly supporting Yeddyurappa's party and six BJP legislators are with BSR Congress, he said.
The Congress leader defended his party's decision of not moving a no-confidence motion against the government, saying "unless we get the support of JDS and BJP rebels, such a motion will not succeed.
Considering all these issues, we did not move the motion in the just concluded assembly session".
He said the Governor told the delegation that he would look into legal and constitutional aspects.
