1. (1) If Assembly Bill 1507 of the 2019–20 Regular Session amends Section 47605.1 and becomes operative on January 1, 2020, and the charter school is required to submit a petition to the governing board of a school district or county board of education in an adjacent county in which its existing resource center is located in order to comply with Section 47605.1, as amended by Assembly Bill 1507 of the 2019–20 Regular Session, or to retain current program offerings or enrollment.
2. (2) If a charter school is required to submit a petition to a school district or county board of education in which a resource center is located in order to comply with the court decision in Anderson Union High School District v. Shasta Secondary Home School (2016) 4 Cal.App.5th 262, or other relevant court ruling, and the petition is necessary to retain current program offerings or enrollment.
3.
