Hassan Karim claimed history and historical records noted that Johor was an independent state.

He said unlike Melaka, Penang and Singapore, Johor was not considered part of the Straits Settlements.

“The call by TMJ has basis,” the Pasir Gudang MP said in a statement, referring to Tunku Ismail’s moniker.

Last week, Tunku Ismail called for changes in the federal system, saying Johor should be treated as a partner by Putrajaya, and suggested that Johor-based political parties unite in a coalition known as Gabungan Bangsa Johor.

He also expressed hope that “at least 20% to 30%” of Johor’s revenue will go back to the state in the future.

Hassan said while there were those who felt that Tunku Ismail’s call was not in line with the Federal Constitution, one should look at the suggestion in totality.

“We should not be confined by the interpretation of the Federal Constitution which was drawn up by the Reid Commission for our British colonisers,” he said.

He said Johor remained outside the Federated Malay States, comprising Pahang, Selangor, Perak and Negeri Sembilan, established in 1895 by the British government.

Johor also voluntarily became part of the Unfederated Malay States, but maintained its sovereignty, which was recognised by the British.

“Therefore, TMJ’s call for Johor to be treated as a federal partner like Sabah and Sarawak is not nonsensical,” he said.
