Angel Law primarily represents environmental organizations, citizen groups and individuals in administrative proceedings before public agencies and in legal actions in courts at every level, emphasizing enforcement of:
- Environmental disclosure requirements and legally mandated procedures of environmental review;
- Substantive laws regulating land use and resources protection such as coastal, water quality, planning and zoning, subdivision and civil penalty statutes, as well as local coastal programs, general plans and local ordinances.
- Constitutional and statutory open meeting (“Brown Act”) requirements.
- Election laws governing local initiative and referendum processes.

Angel Law's representation of Save Open Space Santa Monica Mountains, Inc., the Sierra Club and a local community organization in complex litigation culminated in two appellate victories that spearheaded public acquisition of King Gillette Ranch, the crown jewel of the 153,000-acre Santa Monica Mountains National Recreation Area.
