Hey folks, saw a question on a Facebook forum that had an answer I didn't agree with, wanted to get some additional input. The question essentially involved a group of key stakeholders approaching the project manager indicating they didn't feel the project should have been approved and wouldn't bring benefit to the organization and what the PM should do. The two viable answers were:
A) Facilitate a discussion with the group to review the business case

Raise the issue to the project sponsor.
The person who posed the question indicated that the answer was A, but I feel it should be B. The project manager does not have responsibility for the business case, the sponsor does. Anything that could pose risk to the viability of the project should be raised to the sponsor in my opinion. I don't feel the business case is within the PM's authority. Am I off-base with my analysis of this question?
