Lol this isn't Puntland, Somalilanders know what sovereignty is. We just don't recognize Somalia's sovereignty over Somaliland which is why we made the deal with the UAE unilaterally.
Lack of funds didn't stop Somalia to take Kenya to court over the sea boundaries. They can also take the UAE to court if they want to.
The real reason Somalia wouldn't want to take it to court is because then the legal status of Somaliland will come into question.
The government in Somalia knows that their legal claim over Somaliland is weak so their tactic has always been to avoid having to deal with Somaliland and hoping it'll eventually collapse on its own.
But now that Somaliland is signing deals with other nations as a defacto state, the pressure is now on Somalia to do something or else be seen as forfeiting their claim to sovereignty.
I'm very interested in seeing how things will develop
The FGS has the same jurisdiction over Somaliland as it does over Puntland, de-jure. No one, other than the government of Somaliland questions Somalia's legal right to control all of its territory.
That question literally cannot be raised in any international court because Somalia is a UN member state. Any attempt to raise that question in international court would be an act impugning the territorial integrity of a UN member. It also could not be raised because Somalia's standing in the case would be immediately recognized by the UAE, which would be the counterparty if this case were to ever come to court.
