Annotation	Some extensions of the Standard Model of particle physics allow for Lorentz invariance and charge -parity-time invariance violations. In the neutrino sector strong constraints have been set by neutrino -oscillation and time-of-flight experiments. However, some Lorentz-invariance-violating parameters are not accessible via these probes. In this work, we focus on the parameters oao3 thorn of thorn 00, oao3 thorn of thorn 10, and oao3 thorn of thorn 11 which would manifest themselves in a nonisotropic beta-decaying source as a sidereal oscillation and an overall shift of the spectral endpoint. Based on the data of the first scientific run of the KATRIN experiment, we set the first 90% confidence-level limit on joao3 thorn of thorn 11 j of <0.9 x 10-6 GeV to 3.7 x 10-6 GeV, depending on the phase. Moreover, we derive new constraints on oao3 thorn of thorn 00 and oao3 thorn of thorn 10.
