KUALA LUMPUR - DAP MP Tony Pua will file for a judicial review against the Immigration Department's move to bar him from leaving the country if it fails to furnish a reason within the week.
The party's legal bureau chief Gobind Singh Deo said the Federal Government had gone beyond reasonable expectations by barring Pua without saying why it did so.
"If people can be stopped arbitrarily, it would strike hard on the duty of an MP, who may be required to leave the country," he said.
He asked if the ban was linked to the possibility that police were investigating the Petaling Jaya Utara MP.
Gobind also told Inspector-General of Police Tan Sri Khalid Abu Bakar to stop playing games and name the opposition leader accused of meeting former PetroSaudi International executive Xavier Andre Justo in Singapore.
"What are you waiting for? It's been more than a week and there's still no revelation of who the MP is," he said during a press conference at the DAP headquarters here.
Pua was scheduled to board a 3.15pm flight to Yogyakarta, Indonesia, from KLIA2 when he was stopped by Immigration officers.
Others barred from leaving the country are managing director of SRC International Sdn Bhd and former 1MDB chief investment officer Nik Faisal Ariff Kamil, The Edge Media Group owner Datuk Tong Kooi Ong and PKR MP Rafizi Ramli.
Khalid had said that police would be recording statements from those who met Justo in Singapore following a statement by Thai police that the former PetroSaudi executive had met opposition leaders there.
The Swiss national is being investigated in Thailand over accusations of blackmailing his former employer with documents he took from the company when he left in 2011.
He is also alleged to have sold the documents to a group comprising Malaysians and a British national who then allegedly used them to discredit 1MDB.
