The latest legal news in short bursts: Coastal Commission can't allow seawalls on projects built after 1976, ED1 revisions don't apply prospectively, and La Cañada Flintridge housing element appeal is moot.

Reversing a trial judge, an appellate court ruled that a seawall can be built to protect an apartment complex built in 1972 -- but not an adjacent condo building built in 1984, eight years after the Coastal Act was passed.
