Not if, but when. There have been times in history when a decision from the Supreme Court is wrong. The number is rather low, but, the effects can be huge. Citizens United may be one of the worst decisions in the history of this country. Those effects may be the outright loss of democracy. (Some references are at the end of this post.)
Per our current constitution there is no authority greater than the Supreme Court. The founders did not consider the problem of a court run amuck. What can be done to fix the problem. There currently exist three possible solutions. One, impeach one or more justices. This is a problem because it is a majority that made the wrong decision. To make a change, five or more justices must be removed. That is just not possible. Second is to endure the situation and wait for a majority of the justices to die. This also is a bad solution. Third is to amend the Constitution. An extremely high hurdle and out of proportion to a simple bad decision.
In other words, there are no checks and balances upon the Supreme Court.
We need a Constitutional Amendment that creates some checks and balances. Here is a suggested concept.
There are 13 appellate courts, the last step before the Supreme Court. If some number of the appellate courts, maybe two-thirds, should have the authority to declare that a SCOTUS ruling is wrong. And presume that they write a very specific opinion. Then they have the authority to require the Supreme Court to immediately revisit the decision, and require that court to consider the appellate ruling as a constitutional mandate.
For an example consider the Citizens United decision. Presume that those courts write an opinion that that only U.S. Citizens eligible to vote may take any action to affect the election or appointment of any government official. Because, in part, the Constitution does not grant corporations any legal standing regarding elections and appointments. SCOTUS would be required to immediately revisit the Citizens united decision. Further, if any SCOTUS judge refuses to abide by the appellate decision, the appellate courts should have the authority to remove that justice from the court.
Another parallel path is for Congress to declare a ruling unconstitutional. Maybe another is for the states to declare a ruling improper. Again, not an amendment, a declaration that a ruling is wrong. But this is already too long. Reader comments are solicited.

This site lists their nine worst decisions with Citizens United being last. I put it first because it is playing a huge role in the destruction of democracy. Citizens Unites sells elections to the highest bidder.
