The GP is taking a restricted meaning of "ambiguity", where the ambiguity is within the laws relevant to the case being appealed.

But cases that go to the Supreme Court of the United States are often cases where the "ambiguity" is on how the US constitution should be interpreted and applied.

In a practical sense you're not going to be able to codify the US constitution into code. It's even a well received "feature" that constitutions are sometimes a bit ambiguous, see: https://en.wikipedia.org/wiki/Living_Constitution
