The failure of the then Immigration Department director-general to produce a letter purportedly by inspector-general of police Khalid Abu Bakar to the High Court had raised doubts over his decision to bar DAP parliamentarian Tony Pua from travelling overseas.

In his submission during Pua’s judicial review application to quash the travel ban today, Pua’s counsel, Gobind Singh Deo, argued how the onus was on the respondent (Immigration Department director-general) to establish that there was, beforehand, such a letter.

“Reference was made to the letter but the letter was never produced,” he said.
