4th degree tears and forced cesareans

I think I've linked to the At Your Cervix blog before, but I wanted to mention it again. She is a L&D nurse and recently met a woman who, after two 4th degree lacerations (thanks, most likely, to her episiotomies), was coerced into having a cesarean section. Read more about it here. I have heard of women threatened with court-ordered cesareans for other reasons, but never because of a history of 4th degree tears.
