Recent measurements indicate that the previously established upper limit forthe $\gamma$-decay branch of the $3_{1}^{-}$ resonance in $^{12}\textrm{C}$ at$E_{x} = 9.641(5)$ MeV may be incorrect. As a result, the $3_{1}^{-}$ resonancehas been suggested as a significant resonance for mediating the triple-$\alpha$reaction at high temperatures above 2 GK. Accurate estimations of the$3_{1}^{-}$ contribution to the triple-$\alpha$ reaction rate require accurateknowledge of not only the radiative width, but also the total width. Inanticipation of future measurements to more accurately determine the$\gamma$-decay branch of the $3_{1}^{-}$ resonance, the objective of this workis to accurately determine the total width of the $3_{1}^{-}$ resonance. Anevaluation was performed on all previous results considered in the currentENSDF average of 46(3) keV for the physical total width (FWHM) of the$3_{1}^{-}$ resonance in $^{12}\textrm{C}$. Significant unaccounted-foruncertainties and a misstated result were discovered in these previous results,leading to an invalid ENSDF average. In this work, the new global\textbf{R}-matrix analysis performed on direct-reaction data yields a formaltotal width of $\Gamma(E_{r}) = 46(2)$ keV and an observed total width of$\Gamma_{\textrm{obs}}(E_{r}) = 38(2)$ keV for the $3_{1}^{-}$ resonance. Anobserved total width of $\Gamma_{\textrm{obs}}(E_{r}) = 38(2)$ keV isrecommended for the $3_{1}^{-}$ resonance in $\mathrm{^{12}C}$. This observedtotal width should be employed for future evaluations of the observed totalradiative width for the $3_{1}^{-}$ resonance and its contribution to thehigh-temperature triple-$\alpha$ reaction rate.
