Background<\/h2>\n

California’s coastal zone is managed under a partnership system created by the California Coastal Act of 1976. Each city and county along the coast adopts a Local Coastal Program (LCP) \u2014 a planning document approved by the California Coastal Commission that spells out where and how development can occur in that jurisdiction. After the Commission certifies an LCP, the local government issues coastal development permits in most cases. The Coastal Commission keeps a backstop role: in defined circumstances, it can hear an appeal of a local permit decision and effectively re-decide whether the project should be allowed.<\/p>\n

Shear Development Co. applied to San Luis Obispo County in 2017 for a coastal development permit to build single-family homes on a developed parcel in Los Osos. The County approved the permit in 2019. The Coastal Commission appealed the County’s decision to itself and, in 2020, denied the permit. The Commission asserted two grounds for appellate jurisdiction. First, it concluded the parcel was within a “sensitive coastal resource area” (SCRA) \u2014 a category protected under the Coastal Act and the County’s LCP. Second, it concluded the parcel allowed more than one “principal permitted use” under the LCP, which it argued was enough to trigger appeal rights to the Commission.<\/p>\n

Shear sued, arguing the Commission had no appellate jurisdiction on either ground. The trial court sided with the Commission on the SCRA ground; the Court of Appeal affirmed. The County, which had granted the permit, supported Shear’s position as amicus curiae. The Supreme Court took the case to clarify how courts should review such jurisdictional disputes and to decide which entity’s reading of the LCP \u2014 the Commission’s or the local government’s \u2014 should prevail.<\/p>\n

The Court’s Holding<\/h2>\n

Chief Justice Guerrero, writing for a unanimous court, reversed and held that the Coastal Commission lacked appellate jurisdiction over Shear’s permit. Four key conclusions drove the result.<\/p>\n

First, when the Commission’s appellate jurisdiction turns mainly on interpreting an LCP rather than on factual disputes, the reviewing court must exercise its own independent judgment. An LCP is enacted local law, and judges \u2014 not agencies \u2014 have the final word on what such law means. Courts do not give substantial deference to the Commission’s reading just because the Commission has expertise; deference depends on the analysis below.<\/p>\n

Second, when the Commission and a local government both administer the same law and offer conflicting interpretations, courts should apply the multi-factor framework established in Yamaha Corp. v. State Board of Equalization. Under Yamaha, deference depends on factors like the technicality of the issue, the agency’s expertise, and the consistency of the agency’s position. Where, as here, those factors do not clearly favor either entity, neither side gets the benefit of deference and the court interprets the law on its own.<\/p>\n

Third, the parcel was not in a sensitive coastal resource area. The Commission rested almost entirely on a single map (Figure 6-3) in the LCP, but the figure did not support the Commission’s reading and the LCP read as a whole pointed in the opposite direction. There was therefore no SCRA-based appellate jurisdiction.<\/p>\n

Fourth, the Commission cannot take an appeal simply because a site has more than one principal permitted use. The Coastal Act gives the Commission appellate jurisdiction when a development is not designated as a principal permitted use of the site. If the project is for one of the principal permitted uses listed in the LCP, the Commission has no appellate role, even if the LCP allows other principal uses too. Because Shear’s residential development was a listed principal use of the parcel, the Commission lacked jurisdiction on this basis as well.<\/p>\n
