All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
The sacrifice has nothing to do with performing the rituals of Hajj or not. If it is assumed that the Hajj was not performed in any given year for any reason, then it is prescribed for people to offer the sacrifice and not abandon it just because the Hajj is not organized.
We do not know of any of the scholars, neither the Hanafi School of jurisprudence, nor any other Schools or scholars, who has ever conditioned the legitimacy of the sacrifice on the performance of Hajj.
Allah Knows best.
