The mutual inclination ψ between orbits within multi-planetary systems is difficult to measure directly. Through a joint analysis of RVs, Hipparcos-Gaia absolute astrometry and relative astrometry of JWST, \citet{Bardalez2025} recently found two possible values of ψ_(bc)=32_(-15.1)^(+13.6)° and ψ_(bc)=145.0_(-11.1)^(+15.8)° for the nearby, non-transit planet system, 14\,Her. By incorporating additional astrometry from Gaia second data release (DR2), we have further constrained the orbital orientation of 14\,Her\,b, resulting in a definitive and unambiguous mutual inclination of ψ_(bc)=35.3_(-7.3)^(+6.8)°. The unusual misaligned orbital architecture of 14\,Her system may serve as a benchmark for dynamical studies.
