Did you bother to read it ?,
I expect not.
In other words scumbus JohnRoberts is your final answer ? !
The 14th amendment to the U.S. Constitution which establishes birthright citizenship and how it's obtained, also superseded the Supreme Court's horrendous decision in Dred Scott v. Sandford... A decision which should never have been handed down
To amend your constitution, you don't get 9 judges in a room and change it... You amend it by the established formula laid out in article 5 of the constitution.
Article 5 of the US Constitution establishes the amendment process, requiring a two-thirds vote in both houses of Congress or a national convention requested by two-thirds of state legislatures for proposals. Ratification requires approval by three-fourths of states (via legislatures or conventions). It ensures the Constitution can evolve while requiring high consensus.
The last amendment passed via that process was the 27th which proposed to Delay laws affecting Congressional salary from taking effect until after the next election of representatives. That amendment was proposed in September of 1789, and finally passed on May 7, 1992... 202 years, 223 days after it was first proposed.
So if you really want to change the birthright citizenship which has been established by the 14th amendment to the constitution, don't hold your breath too long... You're going to need a lot more than 9 dumb judges who think they can do that with a simple ruling.
Thankfully, the 6 conservative justices currently on the court always defer to the established constitution of the United States of America and that means birthright citizenship will be maintained by the current court. If you are hoping for some other nonsensical ruling... Don't count on it.
