Lawful Evil characters are the ultimate rules lawyers- while they too see social order as important, they have no problems exploiting loopholes and making sure the law benefits their interests above all others.
I'd actually see manipulation of the law for personal advantage as a relatively weak manifestation of lawful evil. A purer form would be dedication to a worldview built around morally repugnant rules and structures.
Belief that the strong deserve to rule over the weak. Commitment to social and legal structures founded on racism, misogyny and the like. Making a show of gratuitously brutal punishments in order to keep people in line. To me, these are the hallmarks of lawful evil.
