How to use "constitution" in a sentence

A great lover of the British Empire has said that under the British constitution even a successful rebellion is perfectly constitutional, and he quotes historical instances, which I cannot deny, in support of his claim

But I do venture to suggest that it will be highly unconstitutional in the midst of this unconstitutional Government, - in the midst of a nation which has built up its magnificent constitution, - for the people of India to become weak and to crawl on their belly - it will be highly unconstitutional for the people of India to pocket every insult that is offered to them; it is highly unconstitutional for the 70 millions of Mohammedans of India to submit to a violent wrong done to their religion; it is highly unconstitutional for the whole of India to sit still and cooperate with an unjust Government which has trodden under its feet the honour of the Punjab.
