An oral statement which has never been transcribed in any fashion is not a "statement" within the meaning of the Act. Moreover the Act does not require law enforcement officers to make any record of an interview, nor to submit interview notes to the witness for approval so as to generate a statement which is producible under the Act. Notes that are signed, adopted or approved by the witness are generally subject to subpoena. Those that are not cannot be ordered to be produced. Notes that are only of one word references and short phrases are not producible. Investigator's notes made from memory several days after interviewing a witness are not "verbatim" under the meaning of the Act, and hence not subject to subpoena.
