An historical society which had donated artifacts to a museum with rights to notice of any sale of the artifacts, a share of any proceeds of sale of any artifact, and an acknowledgement of its former ownership, did not have standing to intervene in a petition to deviate from the organizational documents of the museum in order to change its management because the society had no “substantial, direct, and immediate” contractual interest that was affected by the deviation, was not a named beneficiary of the museum, and had no “special interest” in the museum separate from its contractual rights.
