My opinion Was negative. But i know article 70 ware positive Side also good 

Article 70 is "A person elected as a Member of Parliament at an election at which he was nominated as a candidate by a political party shall vacate his seat 

1)If he resigns from that party or votes in

2)Parliament against the party

i Think  it’s not right Properly  because Bangladesh is a Republic country 

1) Blocking the Citizen Rights

2)Impede the public interest

3)Contradiction in the constitution (Democracy)

There is a conflict between Article 1, 8, 11' and 'Article 70(1)' in the constitution of Bangladesh, According to the Article 1 we the people of sovereign People's Republic of Bangladesh. Article 8 describes the fundamental rights of Bangladeshi citizen. We know that there are four fundamental rights in our constitution and democracy is the one of them. In addition in the Article 11 of our constitution are talks about the democracy and human rights. However, Article 70(1) does not fulfill the above three articles condition 

It’s my opinion
