Does my case get thrown out if they didn't read Miranda?
No, and this expectation causes real harm — people decline to take a case seriously because they're waiting for a dismissal that isn't coming.
A Miranda violation excludes the statements obtained in violation. The prosecution proceeds on everything else it has.
Where the two can converge: if the statement was the State's case — a confession in a case with no physical evidence, or an admission that supplies an element — suppressing it can leave the State unable to proceed. But that's a consequence of what remains, not an automatic result.
Also worth knowing: a statement suppressed for a Miranda violation can sometimes still be used for limited purposes, such as impeaching testimony if the defendant takes the stand and says something different. So "suppressed" doesn't always mean gone entirely.
The productive question is what the State has besides the statement. That's an assessment of the whole file, not a single ruling.
Don't decide anything based on a general answer. Decide it after somebody reads your file. ---
