  We propose a manifestly gauge invariant effective tensor operator that can
account for the $ CP $ asymmetry anomaly in $ \tau $ decays, contrary to the
claim made in literature. Additionally, this operator can also help in
resolving the long-standing discrepancy in the value of $ V_{us} $ extracted
from inclusive $ \tau $ decays. By construction, the operator evades bounds
from neutron electric dipole moment, while keeping the extraction of $ V_{us} $
from exclusive $ \tau $ decays unaffected. We explicitly provide a
renormalizable model of flavor symmetries that yields the desired effective
tensor operator.
