Does the Indian Removal Act of 1830 uphold the Declaration of independence? why or why not?

No, It doesn't uphold the Declaration of independence.  

Explanation:

The Indian Removal Act was signed into law on May 28, 1830, by United States President Andrew Jackson. The law authorized the president to negotiate with southern Native American tribes for their removal to federal territory west of the Mississippi River in exchange for white settlement of their ancestral lands.

Congress passes the Indian Removal Act, sanctioning the forcible relocation of Creek, Chickasaw, Cherokee, Choctaw, and Seminole tribes to land allotments west of the Mississippi river. Ninety-four removal treaties follow the bill's enactment. From 1835 to 1838, Cherokee and Creek are forcibly removed from the Southeast onto reservations. Nearly one quarter die along what became known as the “Trail of Tears.”

In Washington, D.C., the delegates of the people of Texas officially and unanimously declare their independence. Jackson recognizes the independence of Texas but declines to address annexation in light of threats by Mexico and its concerns about security.
