Photodisintegration of polarized ${}^3\mathrm{He}$ by linearly or circularly polarized photons offers a rich choice of observables, which can be calculated with high precision using a rigorous scheme of three-nucleon Faddeev equations. Using the (semi)phenomenological AV18 nucleon-nucleon potential combined with the Urbana IX three-nucleon force we investigate sensitivity of ${}^3\mathrm{He}$ photodisintegration observables to underlying currents taken in the form of a single-nucleon current supplemented by two-body contributions for $\pi$- and $\rho$-meson exchanges or incorporated by the Siegert theorem. Promising observables to be measured for two- and three-body fragmentation of ${}^3\mathrm{He}$ are identified. These observables form a challenging test ground for consistent forces and currents being under derivation within the framework of chiral perturbation theory. For three-body ${}^3\mathrm{He}$ photodisintegration several kinematicaly complete configurations, including SST and FSI, are also discussed.
