Guys, evidences are enough that the result would be out by 12th April only.
First, IIM-L's website once said that final list would be out by 12th April only.
In a board meeting of IIM-A over recent reservation and SC issue, directors of IIM-A have clarified that they would
wait until 12th April for a vacation on the stay on the moves of the institutes. The latest orders of Supreme Court asks institutes to disconsider 27% reservation for now, as a result of which the normal process of preparing the list (without extra 27% OBC reservation) stays. If this stay is vacated, then they would declare the result keeping reservation in mind or else they would consider OBCs as general candidates only (just like the last year) but the subsequent course of action (like merging of final lists of general and OBCs etc..) is not clear as yet.
And it has been seen in the previous years that IIM-A is usually the first IIM to declare its result and other IIMs declare it within its 1-2 days.
So my take: 12-14 April for all IIMs
