Mahāsaṅghika Vinaya
Bhikkhunī Vibhaṅga
Suspension 2
Two rules on “unfounded,” as explained in detail in the bhikkhu rules. This is what the World-honored One said.
Final Ruling
If a bhikkhunī out of hostility and dissatisfaction, slanders a pure, innocent bhikkhunī with an unfounded pārājika offense, wanting to destroy that bhikkhunī’s monastic life, and at a later time, whether examined or not examined, says: ‘This matter is unfounded. I said this because I was harboring hostility,’ it’s an immediate offense.
Explanation
This is what the World-honored One said.
