1. What is an easier way of stating "That the people have the right to elect their own Legislature"

That the people can elect their own government.

2. What is simpler way of stating "That no act of the Dominion Parliament (local to the territory) be binding ont he people until sanctioned by the Legislature of the Territory"

Can someone please check #1 for me and help me with #2? Thanks very much.

1. Yes, that's fine, or ... that the people can elect their own representatives.

[Keep in mind that is not a complete sentence. How are you planning to use that clause?]

2. Maybe this ...
That any act of the Dominion Parliament be mandatory until approved by the Legislature of the Territory.
