      abstract     = {The CP properties of the Higgs boson are studied in the
                      vector-boson fusion production mode. The analysis exploits
                      the decay mode of the Higgs boson into two $τ$-leptons
                      using 140 fb$^{-1}$ of proton-proton collision data at
                      $\sqrt{s}=13$ TeV collected by the ATLAS experiment at the
                      Large Hadron Collider. Results are obtained using the
                      Optimal Observable method. CP-violating interactions between
                      the Higgs boson and electroweak gauge bosons are considered
                      in the effective field theory framework, with the
                      interaction strength described in the HISZ basis by
                      $\tilde{d}$, and in the Warsaw basis by $c_{H\tilde{W}}$,
                      $c_{H\tilde{B}}$, and $c_{H\tilde{W}B}$. No deviations
                      relative to the Standard Model are observed, and limits are
                      obtained on the strength parameters. The $\tilde{d}$
                      parameter is constrained to the interval [$-0.012, 0.044$]
                      at the 95\% confidence level while $c_{H\tilde{W}}$ is
                      constrained to [$-0.24, 0.83$], when considering both linear
                      and quadratic effects of physics beyond the Standard Model.},
