The Supreme Court has never ruled on parents who are here illegal.
All of the Court cases was on parents who were not citizens but was here legally.
The Supreme Court has never explicitly ruled on whether children born in the United States to illegal immigrant parents are entitled to birthright citizenship via the 14th Amendment, but it has generally been assumed that they are.

Assuming is not the actual facts.
It needs to be taken up with the Supreme Court.
Sure they did. In INS v. Rios they were faced with applying Section 244(a)(1) of the Immigration and Nationality Act which allows the Attorney General to suspend an alien's deportation if the alien has been present in the United States for a continuous period of at least seven years, is of good moral character, and demonstrates that deportation w
ould result in extreme hardship to the alien or to the alien's spouse or child, who is a United States citizen. The facts of this case were:
"Respondents, a married couple, are natives and citizens of Mexico. Respondent husband illegally entered the United States in 1972. Apprehended, he returned to Mexico in early 1974 under threat of deportation. Two months later, he and respondent wife paid a professional smuggler $450 to transport them into this country, entering the United States without inspection through the smuggler's efforts. Respondent husband was again apprehended by INS agents in 1978. At his request, he was granted permission to return voluntarily to Mexico in lieu of deportation. He was also granted two subsequent extensions of time to depart, but he ultimately declined to leave as promised. INS then instituted deportation proceedings against both respondents.
By that time, respondent wife had given birth to a child, who, born in the United States, was a citizen of this country. A deportation hearing was held in December, 1978. Respondents conceded illegal entry, conceded deportability, but requested."
Now, if it were not settled law that their child, born to them while they were here illegally, is a US citizen, they had no case. The Supreme Court, however, stated that because their son was a US citizen, the law applied. It is a fact that you cannot dispute that the 1000 or so children who will be born today to illegal aliens will be citizens. Nothing you can do about it.
