The bench of justices Quamrul Islam Siddique and Razik-Al-Jalil on Tuesday ordered the home secretary and passport department chief to come up with explanations within three weeks.

The BNP's Senior Joint Secretary General, Rizvi submitted his old passport on Dec 10 last year and applied for a machine-readable one.

He was supposed to get his new passport on Dec 31, but the authorities did not deliver it to him.

In May this year, Rizvi moved the High Court after a legal notice served to the authorities had gone unanswered.
