There is a real problem now with this court verdict.
The Brussels region has another legislation than Flanders, and the law is the law.
Flanders will not change its noise limits. ( fearing that more business would go to Liege and Charleroi )
I proposed in the past a legaly acceptable solution: keep on flying above Brussel and pay the fines. Thoses fines could be financed by an increased airport tax.
Everybody who books a ticket living in a postal code outside Brussels receives
a discount.
This is 100 % legally acceptable after I have found out about the ferry and Chunnel crossings, cheaper for UK citizens than for continentals. ( there is an European declaration about this: you are free to give a discount to who you want, you are not free to increase the price depending on origin )
So, inhabitants from Flanders ( and maybe Walloon as well, I don't know their legislation and noise level ) will pay less than the inhabitants from the region that allowed this stringent legislation to be implemented.
Again, it is no discrimination. It is legally acceptable. And the funny thing: it can be implemented immediately.
Before all dear members denounce me crazy: I live in Bruges. A visit to the Belfort Tower costs 8 €. But inhabitants of Bruges get in for free, by showing their ID with the address. It is legally accepted because it is anounced as a discount

( and guess who complained about this "discrimination"

)
