Let be the disk or a compact, connected surface without boundary different from the sphere and the real projective plane , and let be a compact, connected surface (possibly with boundary). It is known that the pure braid groups of are bi-orderable, and, for , that the full braid groups of are not bi-orderable. The main purpose of this article is to show that for all , any subgroup of that satisfies is not bi-orderable.
