How the pilot in command justified a departure at that point is hard to understand and illegal under under US rest rules.
Their rest rules are obviously different. Under 117, you could accomplish this with a 19 hr FDP if there are 4 pilots. It would be illegal with only 3 pilots though. 3 or 4 pilots, I'd have probably been done after setting the brakes in OAK.
