In Buehler v. Oregon-Washington Plywood Corp. (1976) 17 Cal.3d 520, an easement for the transport of lumber had been granted in resolution of a previous lawsuit over the scope of an earlier easement. The court noted that later paragraphs of the grant limited the assignability of the easement to persons owning specified interests in the tracts originally involved, and found that these provisions "suggest an intention on the part of the contracting parties that the easements be used solely for the purpose of logging operations relating to the utilization of timber rights in the original tracts." ( Id. at p. 528.) Accordingly, it found that these terms were reasonably susceptible of an interpretation that the easement was intended to be so limited, and that extrinsic evidence was properly admitted on the subject.
