We formulate an approximate relativistic framework for an analysis of the \vec ³He ({\vec e},e' p)pn and \vec ³He ({\vec e},e' n)pp reactions. Restricting the rescattering series to one term linear in the two-nucleon (2N) t-matrix we incorporate various relativistic features when calculating a nuclear current matrix element. These relativistic ingredients encompass the relativistic ³He wave function based on the concept of the Lorentz boosted nucleon--nucleon potential together with the boosted (2N) t-matrix, relativistic kinematics and relativistic single-nucleon current operator. This allows us to estimate the magnitude of certain relativistic effects not included in the standard nonrelativistic approach. A more complete inclusion of relativity would require that the current operator obeys the covariance equations and the final three-nucleon (3N) scattering state with complete final state interactions (FSI) should be properly boosted. We provide some discussion on those issues.
