I couldn't agree more with Justice Blease.
It's true that unlicensed contractors can't recover money, even for work they've done. But David Ball was licensed. Sure, his d/b/a was "Clark Heating and Air Conditioning," whereas here he did the work as "Clark Air Conditioning and Heating" -- essentially, transposing the two types of work.
But he still has a license. He should be paid.
Judge Chang (up in Sacramento) held otherwise. Glad she was reversed.
Doctrinally, Justice Blease is correct. Ditto for the equities.
