According to the declaration of independence, which situation justifies open rebellion against a government

According to the Declaration of Independence, if the government took from the people their natural rights (to life, to liberty and to the pursuit of happiness), the people would have the right to rebel against it.

Explanation:

The right of rebellion is a right recognized to the people against rulers of illegitimate origin or who having legitimate origin have become illegitimate during their exercise, which authorizes civil disobedience and the use of force in order to overthrow and replace them by governments that have legitimacy.

This right can be considered implicit in the Declaration of Independence of the United States of 1776, which in its most famous paragraph states:

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security".
