Well there HAVE been warrants that have been ruled after the fact to be too broad because they asked for material that could not reasonably be related to crime being investigated.* But I’m not sure that would (legally) justify a third party to fail to provide the documents ordered.
- one could imagine that when investigating an accident, the phone records immediately before the accident would be quite relevant (was the driver texting) but that last months records would be thrown out, even if there was evidence of a (different) crime.
