"I thought the practice of misusing Raj Bhavans to over throw legitimately elected governments was a thing of the past, sadly not!" Omar wrote on twitter.
He was referring to bizarre turn of events in Arunachal Pradesh, where opposition BJP and rebel Congress MLAs yesterday got together in a local hotel to "vote out" Chief Minister Nabam Tuki and to "elect" a rebel Congress MLA in his place.
"J&K has paid a very high price for the machinations of the Governor in 1984. Let's hope developments in Arunachal don't have similar fallout," he added.
National Conference President and the then Chief Minister Farooq Abdullah was dismissed from office by then Governor Jagmohan on July 2, 1984 following a defection in his own party led by his brother-in-law Ghulam Mohammad Shah.
In a statement, Omar said it is the duty of the state government to fully and competently defend the status of the Constitution of Jammu and Kashmir and prevent any central laws from "undermining" the autonomous character of the state, its Constitution and the essence of Article 370.
"Unfortunately, the PDP-BJP government, it seems, has absolved itself of this duty in what could be an understanding it has with the central government in this context.
"It is important to put the Instrument of Accession, the state's Constitution and the state's Special Autonomous Status in the right perspective while dealing with such cases and while representing the State in the SC - and that clearly has not happened here," the NC leader said.
"In light of this, two pertinent questions need to be answered by the PDP and its alliance government in the state.
"One, since we were told PDP has entered into an alliance with the BJP with a concrete agreement from the Union Government and the BJP that the state's special status would be protected, why is the Union Government using the judicial route to subvert certain attributes of the state's constitutional character?
Accusing PDP of contradictions over the issue, Omar said, "In what could be yet another volte-face by the PDP, it seems they have decided to facilitate the long-cherished desire of their alliance partner to circumvent and subvert the Constitution of the State and attributes of Article 370".
The former chief minister said his party would consult eminent constitutional lawyers, jurists and civil society groups "in an effort to prevent the subversion of the state's Constitution and autonomous character".
