Other than precedent, what could keep the President from simply

[Old Troop]

ignoring a Supreme Court ruling against his program?

[madinmaryland]

1. The threat of impeachment and the fact he would never get reelected if he did that. nt

[arcane1]

2. Ignoring it changes nothing

it's not like he's personally managing the program himself.

3. Impeachment, I would hope

Seriously... WTF?

[Xithras]

4. Congress.

The Supreme Court decides what is legal and what is illegal. Acting contrary to the Supreme Court is, by definition, illegal. Presidents who engage in illegal acts will rapidly find themselves thrown out of office.

5. Actually the Supreme Court should not be making laws nor should the President.

Congress makes the laws. I don't think the Supreme Court really has the jurisdiction to hear this and change it, but of course it seems they are becoming unelected lawmakers.

7. They have elected a president for you so

their authority seems unending, or so they would have all believe

[PoliticAverse]

6. He would also have to ignore all the subsequent rulings by courts following the Supreme Court....

He will not be able to ignore a ruling overturning the mandate.

8. there should be a way to appeal. This court is basically the tea party

9. Yikes, do you really have to ask such a thing?

Did they not teach you in school about the three branches of government, and that we don't have dictators for president?

What if a future (Republican) president decided to ignore Supreme Court rulings and, say, decided to act against Roe v. Wade or some other court decision?
