Verdict is out: The ban is upheld; no flights between 2300 and 0500.
The ban extends to cover the 17 flights that was exempted until now - it's therefore a total ban on all movements during curfew hours. That means if you're not lined up by 2259, you're shyte out of luck and will be denied take-off clearance - even if you're "only" suffering from a delay and are not actually operating a flight scheduled to depart after 2300. Same goes for landings, if you're not on the ground by 2300 you'll be denied clearance and have to divert to your alternate.
Dark days for LH Cargo, as the verdict effectively eradicates their business case, which is built around the profitability of express freight. If your homebase is in Europe, It is simply not possible to offer an intercontinental express product without operating at night. No night flights = no viable express product = no viable LH Cargo in its present form.
