The chiral low-energy constants cD and cE are constrained by means of accurate ab initio calculations of the A = 3 binding energies and, for the first time, of the triton {beta} decay. We demonstrate that these low-energy observables allow a robust determination of the two undetermined constants. The consistency of the interactions and currents in chiral effective field theory is key to this remarkable result. The two- plus three-nucleon interactions from chiral effective field theory defined by properties of the A = 2 system and the present determination of c{sub D} and c{sub E} are successful in predicting properties of the A = 3, and 4 systems.
