On 8 June 2014, Bangladesh High Court issued a ruling asking the Election Commission, Government of Bangladesh, and Uddin to explain why his parliamentary membership should not be cancelled due to his conviction in the arms case.[3] Two subsequent benches of Bangladesh High Court said they were "too embarrassed" to hear the case and it was delayed.[3]
