Answer: This would depend on how substantial the amount that was not read was. Did he leave out something that was very important, or is it a matter of a couple of words? That would be the first inquiry we would make. The second would be: what was gained, what type of evidence was found, from any questioning after the Miranda? Was it critical to the case? If it’s critical evidence and substantial rights were not explained to you, it could be very important to your case. If no real evidence was gathered, it really doesn’t matter whether the Miranda were read properly or not.
