3.14.35

karmaṇy asamāpte tu yajamānaḥ sīded, ṛtvijaḥ karma samāpayya dakṣiṇāṃ hareyuḥ //

If the sacrificer himself (he who has instituted the sacrifice) dies, then the remaining priests shall complete the sacrifice and carry away the presents. If a sacrificer sends out any priest before completing the sacrifice, he shall be punished with the first amercement. If a sacrificer sending out a priest happens to be a person who has not kept the sacrificial fire, or to be a preceptor or one who has already performed sacrifices, then the fines shall be 100, 1000, and 1000 panas respectively.
