Notes of Decisions

Where witness for the state had testified on direct examination by the state and grand jury testimony of that witness was previously tape-recorded, defendant was entitled, in furtherance of justice, to examine recording. State v. Hartfield, 290 Or 583, 624 P2d 588 (1981)

Notes of Decisions

Copy of letter sent to district court and also to district attorney's office, entering not guilty plea and stating "by copy of this letter I am demanding reciprocal discovery from the District Attorney's office," was insufficient to make formal demand for disclosure of classes of information available under these sections. State v. Sheppard, 32 Or App 345, 573 P2d 1276 (1978), Sup Ct review denied

Specifications, operating instructions and repair and maintenance records for radar device with which arresting officer measured defendant's speed were not discoverable under these sections. State v. Spada, 33 Or App 257, 576 P2d 33 (1978), aff'd286 Or 305, 594 P2d 815 (1979)

These sections afford defendant opportunity to obtain specific and detailed information about state's theory of case and evidence it intends to produce at trial, and purposes that indictments and complaints are designed to serve in criminal cases are now served as well or better by discovery. State v. Strandquist, 57 Or App 404, 644 P2d 658 (1982), Sup Ct review denied

Nothing in discovery statutes prevents state from initiating grand jury investigation of possible criminal activities by potential defense witnesses. State v. Huffman, 65 Or App 594, 672 P2d 1351 (1983)

Where defendant appeals conviction and trial court precluded defense witness because of alleged discovery violation and state being prejudiced, trial court obligated to explore other alternatives to remedy prejudice before precluding witness from testifying.
