We reexamine the contact interaction hypothesis for excess high-Q2 events seen at HERA in e+ p → e+ X scattering. We consider the most general structure of contact interactions insisting on SU(3)C× SU(2)L × U(1)Y invariance. Apart from constraints for e+ e- → q q , Drell-Yan and atomic parity violation experiments, we find stringent constraints from neutrino deep inelastic data. A possible choice of contact terms that escape present bounds is still possible, althought new data from FERMILAB and LEP should further constrain such a possibility.
