Subd. 1. Admissibility of Evidence. An indictment must be based on evidence that would be admissible at trial, with these exceptions:
Subd. 2. Evidence Warranting Finding of Indictment. The grand jury may find an indictment if the evidence establishes probable cause to believe an offense has been committed and the defendant committed it. Reception of inadmissible evidence does not provide grounds for dismissing the indictment if sufficient admissible evidence exists to support the indictment.
Subd. 3. Presentments Abolished. The grand jury may not find or return a presentment.
