  A particle orbiting a misaligned eccentric orbit binary undergoes nodal
precession either around the binary angular momentum vector (a circulating
orbit) or around a stationary inclination (a librating orbit). In the absence
of general relativity, the stationary inclination is inclined by 90 degrees to
the binary angular momentum vector (aligned with the binary eccentricity
vector) and does not depend on the particle semi-major axis. General relativity
causes apsidal precession of the binary orbit. Close to the binary, the
behaviour of the particle is not significantly affected, a librating particle
precesses with the binary. However, we find that the stationary inclination and
the minimum inclination required for libration both increase with the particle
semi-major axis. There is a critical radius beyond which there are no librating
orbits, only circulating orbits, and therefore there is a maximum orbital
radius for a stationary polar orbiting body. The critical radius is within
planet forming regions around binaries with semi-major axis <= 1 au. This has
implications for the search for misaligned circumbinary planets and the radial
extent of polar circumbinary disks.
