We present the first model-independent measurement of the CKM unitarity triangle angle Φ₃ using B^±→ D($ {K}_{\mathrm{S}}^0 $π⁺π^–π⁰) K^± decays, where D indicates either a D⁰ or $ \overline{D} $⁰ meson. Measurements of the strong-phase difference of the D →$ {K}_{\mathrm{S}}^0 $π⁺π^–π⁰ amplitude obtained from CLEO-c data are used as input. This analysis is based on the full Belle data set of $772 × 10^6 B$$ \overline{B} $ events collected at the Υ(4S) resonance. We obtain Φ₃ = ($ {5.7}_{-8.8}^{+10.2} $±3.5±5.7)^° and the suppressed amplitude ratio r_B = 0.323±0.147±0.023±0.051. Here the first uncertainty is statistical, the second is the experimental systematic, and the third is due to the precision of the strong-phase parameters measured from CLEO-c data. The 95% confidence interval on Φ₃ is (–29.7, 109.5)^°, which is consistent with the current world average.
