On June 9, 2020 Governor Murphy signed Executive Order-152, which was effective immediately, and which contained new rules for gatherings. It reads, in part:

1. No indoor gathering may take place in the State, whether on public or private property, unless it adheres to all of the following rules: a. The number of individuals at the gathering shall be limited to 25% of the capacity of the room in which it takes place, but regardless of the capacity of the room, such limit shall never be larger than 50 persons or smaller than 10 persons; b. All attendees at the gathering must wear face coverings at all times except where doing so would inhibit the individual’s health or where the individual is under two years of age; c. If there are individuals organizing or maintaining the gathering, those individuals must wear face coverings whenever feasible, and must wear face coverings whenever they are within six feet of another individual, except where doing so would inhibit the individual’s health; d. All attendees at the gathering are required to be six feet apart from other attendees at all times, excluding immediate family members, caretakers, household members, or romantic partners, as well as excluding a limited number of individuals organizing or maintaining the gathering; e. There may be no contact between attendees, excluding immediate family members, caretakers, household members, or romantic partners, and excluding a limited number of individuals organizing or maintaining the gathering; f. Where the number of individuals at the gathering is 10 persons or fewer, the gathering is not required to comply with Paragraphs 1(a)-(e) of this Order, but all individuals at the gathering should wear face coverings at all times, except where doing so would inhibit the individual’s health or where the individual is under two years of age; g. If there are individuals organizing or maintaining the gathering, they should, where applicable, demarcate six feet of spacing in the area of the gathering to demonstrate appropriate spacing for social distancing, such as through the placement of cones, flags, or other markings; h. Any physical items, including equipment, may not be shared by multiple attendees of the same gathering except for immediate family members, caretakers, household members, or romantic partners, unless such physical items are sanitized before and after use by different individuals; and i. To the degree the gathering requires pre-payment, or seeks donations of any kind, contactless options for pre-payment or donation, such as online or by telephone, must be offered wherever feasible. 
2. No outdoor gathering may take place in the State, whether on public or private property, unless it adheres to all of the following rules: a. The number of individuals at the gathering must be limited to 100 persons or fewer; b. All attendees at the gathering are required to be six feet apart from other attendees at all times, excluding immediate family members, caretakers, household members, or romantic partners, as well as excluding a limited number of individuals organizing or maintaining the gathering; c. There may be no contact between attendees, excluding immediate family members, caretakers, household members, or romantic partners, and excluding a limited number of individuals organizing or maintaining the gathering; d. If there are individuals organizing or maintaining the gathering, they should, where applicable, demarcate six feet of spacing in the area of the gathering to demonstrate appropriate spacing for social distancing, such as through the placement of cones, flags, or other markings; e. Any physical items, including equipment, may not be shared by multiple attendees of the same gathering except for immediate family members, caretakers, household members, or romantic partners, unless such physical items are sanitized before and after use by different individuals; f. Where the number of individuals at the gathering is 25 persons or fewer, the gathering is not required to comply with Paragraphs 2(a)-(e) of this Order. Where the outdoor gathering is a religious service or political activity, such as a protest, the gathering is not required to comply with Paragraphs 2(a)-(e) of this Order; g. Open-air rain tarps, tents, and other outdoor structures shall be allowed solely for the purpose of protecting against foul weather or for shade; h. All individuals at the gathering should wear face coverings at all times where other social distancing measures are difficult to maintain, in accordance with CDC recommendations, except where doing so would inhibit the individual’s health or where the individual is under two years of age, and all attendees must wear such face coverings where required by another Executive Order; and i. To the degree the gathering requires pre-payment, or seeks donations of any kind, contactless options for pre-payment or donation, such as online or by telephone, must be offered wherever feasible. 3. No individual shall be considered in calculating the total number of attendees at the outdoor gathering at any time in which that individual is in a vehicle, so long as that vehicle is either (1) closed, meaning that the windows, doors, sunroofs, and tops of the vehicle are all closed, or (2) more than six feet from any other vehicle or individual. 4. Nothing in this Order shall prevent an individual at a gathering from coming within six feet of another person, coming into contact with another person, going indoors, or leaving their vehicles, if done to protect their health or safety or the health or safety of another individual. 5. Nothing in this Order shall prevent a person at a gathering from momentarily removing their mask to place or receive an item in their mouth, including food or beverage, if done for religious purposes or for their health or safety. 6. Gatherings authorized by this Order are permitted at State Parks and Forests, county and municipal parks, public and private beaches, boardwalks, lakes, and lakeshores; however, consistent with Executive Order Nos. 108, 133, and 148 (2020), counties and municipalities may impose additional restrictions at county and municipal parks in response to COVID-19. 7. Available parking at all State Parks and Forests shall reopen to their full maximum capacity, and available parking at all county and municipal parks may reopen to their full maximum capacity.
