English: The community does not bring [a communal chatas] for tumah of the Mikdash and its kodashim.
Exclusion of Temple impurity — communal chatas does not cover the special prohibitions of Temple impurity.
Tum’at Mikdash ve-kodashav lies outside the reach of the par he’elam davar of the congregation. Even if the Sanhedrin erred concerning those laws and the people acted on the error, the ordinary communal bull is not brought. A different set of offerings addresses Temple impurity.
