Superior Court Judge Mary Jacobson also has rejected some rules the state tried to impose on the protesters.
Jacobson on Monday granted a temporary restraining against the state, saying troopers couldn't confiscate signs or personal property.
The American Civil Liberties Union of New Jersey sued on behalf of protesters who claim their freedom of speech was infringed on when troopers confiscated items they considered unattended.
But Jacobson says protesters can't attach signs to the walls, can't erect permanent structures or use power outlets at the memorial.
The ACLU says the state made up park rules after the protests started.
Another hearing is scheduled for Dec. 19.
