(c) Upon filing the petition, the clerk of the court shall set the hearing date and notify the petitioner and the prosecuting attorney of the date of the hearing. (d) Upon making each of the following findings, the court may reduce or eliminate the prohibition, impose conditions on reduction or elimination of the prohibition, or otherwise grant relief from the prohibition as the court deems appropriate: (1) Finds by a preponderance of the evidence that the petitioner is likely to use a firearm in a safe and lawful manner. (2) Finds that the petitioner is not within a prohibited class as specified in Section 29815, 29820, 29825, or 29900, or subdivision (a) or (b) of Section 29800, and the court is not presented with any credible evidence that the petitioner is a person described in Section 8100 or 8103 of the Welfare and Institutions Code.

It is the intent of the Legislature that courts exercise broad discretion in fashioning appropriate relief under this section in cases in which relief is warranted. However, nothing in this section shall be construed to require courts to grant relief to any particular petitioner.
