LITTLE ROCK, Ark. - A unanimous Arkansas Court of Appeals Division II panel issued an opinion Sept. 25 denying the appeal by a natural gas company of an order to enforce the settlement of a quiet title dispute; the natural gas company argued that the settlement was unenforceable because the parties made a mutual mistake of law (Stephens Production Co. v. Boyd Blackard, et al., No. 12-921, Ark. App., Div. II; 2013 Ark. App. 530).
