8558. Government Code Title 2 Division 1 Chapter 7 Article 2

Three conditions or degrees of emergency are established by this chapter:

(a) “State of war emergency” (not relevant to epidemics)

(b) “State of emergency” means the duly proclaimed existence of conditions of disaster or of extreme peril to the safety of persons and property within the state caused by conditions such as air pollution, fire, flood, storm, epidemic, riot, drought, cyberterrorism, sudden and severe energy shortage, plant or animal infestation or disease, the Governor’s warning of an earthquake or volcanic prediction, or an earthquake, or other conditions, other than conditions resulting from a labor controversy or conditions causing a “state of war emergency,” which, by reason of their magnitude, are or are likely to be beyond the control of the services, personnel, equipment, and facilities of any single county, city and county, or city and require the combined forces of a mutual aid region or regions to combat, or with respect to regulated energy utilities, a sudden and severe energy shortage requires extraordinary measures beyond the authority vested in the California Public Utilities Commission.

(c) “Local emergency” means the duly proclaimed existence of conditions of disaster or of extreme peril to the safety of persons and property within the territorial limits of a county, city and county, or city, caused by conditions such as air pollution, fire, flood, storm, epidemic, riot, drought, cyberterrorism, sudden and severe energy shortage, plant or animal infestation or disease, the Governor’s warning of an earthquake or volcanic prediction, or an earthquake, or other conditions, other than conditions resulting from a labor controversy…,

(Amended by Stats. 2018, Ch. 557, Sec. 1. (SB 532) Effective January 1, 2019.)

This, combined with:

Cal. Gov. Code § 8629 (“The Governor shall proclaim the termination of a state of emergency at the earliest possible date that conditions warrant. All of the powers granted the Governor by this chapter with respect to a state of emergency shall terminate when the state of emergency has been terminated by proclamation of the Governor or by concurrent resolution of the Legislature declaring it at an end.”)

And:

Government Code Title 2 Article 13 8627.5 (b)

(b) The orders and regulations shall be in writing and take effect immediately on issuance. The temporary suspension of any statute, ordinance, regulation, or rule shall remain in effect until the order or regulation is rescinded by the Governor, the Governor proclaims the termination of the state of emergency, or for a period of 60 days, whichever occurs first.

In short:

Results in the stay at home order in California made on March 19th, 2020 to be unlawful if it is continued to be enforced past May 18th, 2020. This means all restrictions made by the initial order were to expire yesterday for California.

Feel free to spread this info, had it brought up by someone that was looking way deeper into this than me, but she isn't the sort that'd publicize it.
