Abstract: We present a measurement of the angle ${\ensuremath{\phi}}_{1}$ of the Cabibbo-Kobayashi-Maskawa unitarity triangle using a time-dependent Dalitz analysis of $D\ensuremath{\rightarrow}{K}_{S}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ decays produced in neutral $B$ meson decay to a neutral $D$ meson and a light meson (${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{(*)}{h}^{0}$). The method allows a direct extraction of $2{\ensuremath{\phi}}_{1}$ and, therefore, helps to resolve the ambiguity between $2{\ensuremath{\phi}}_{1}$ and $\ensuremath{\pi}\ensuremath{-}2{\ensuremath{\phi}}_{1}$ in the measurement of $\mathrm{sin}2{\ensuremath{\phi}}_{1}$. We obtain $\mathrm{sin}2{\ensuremath{\phi}}_{1}=0.78\ifmmode\pm\else\textpm\fi{}0.44\ifmmode\pm\else\textpm\fi{}0.22$ and $\mathrm{cos}2{\ensuremath{\phi}}_{1}={1.87}_{\ensuremath{-}0.53\ensuremath{-}0.32}^{+0.40+0.22}$. The sign of $\mathrm{cos}2{\ensuremath{\phi}}_{1}$ is determined to be positive at 98.3% C.L.
