The context: The author is discussing the Bommai case and its effect.
By invoking the BSD in support of the national governments the SC in effect was liberating the Centre to be a proactive player in fulfilling the aspirations that it, the Court, had certified as high priority goals.

What are the various possible ways that it would lead to crisis.
What can be the other reasons.
The only thing necessary for the triumph of evil is for good men to do nothing.
