How long after non complicated vaginal birth is it safe to perform an open tubal ligation?

I currently work in a high volumen OB/GYN hospital. Today OB filed a complaint against one of our attendings because he will only do a tubal ligation 6 hours after birth. I usually have them wait 30 min after birth just to make sure there’s no bleeding or any funny bussiness (this is a teaching hospital After all). I took a deep on this topic but I didn’t find anything conclusive, what’s you take on this?
