The traditional government system still influences the nation's affairs, leading the federal government to repeatedly attempt to limit its power. Many of these attempts took the form of amendments to the constitution that were supported by the corporate sector to protect what they deemed should be free economic zones.  One such example occurred in early 2010, where the Idid clan, the ruling clan of the Southern Federation, under the leadership of Bilung, the Southern Federation's queen, raised a civil suit against the Koror State Public Lands Authority (KSPLA). The Idid clan laid claim over Malakal Island, a major economic zone and Palau's most important port, citing documents from the German Era. The verdict held that the island belonged to the KSPLA.
