If evidence has previously been subjected to DNA analysis by either the prosecution or defense, the court may order the prosecution or defense to provide all parties and the court with access to the laboratory reports prepared in connection with the DNA analysis, as well as the underlying data and laboratory notes. If any DNA or other biological evidence analysis was previously conducted by either the prosecution or defense without knowledge of the other party, the analysis shall be revealed in the motion for analysis or response, if any. If the court orders DNA analysis in connection with a proceeding brought under this part, the court shall order the production of any laboratory reports prepared in connection with the DNA analysis and may, in its discretion, order production of the underlying data and laboratory notes.
