Intermediate scrutiny for content-neutral regulations

For content-neutral regulations, they should be tested or measured against the intermediate scrutiny, viz.:
  1. The regulation is within the constitutional power of the government;
  2. It furthers an important or substantial governmental interest;
  3. Such governmental interest is unrelated to the suppression of the free expression; and
  4. The incidental restriction on the alleged freedom of expression is no greater than (narrowly tailored with) what is essential to the furtherance of the governmental interest. (Chavez v. Gonzales, 569 Phil. 155, 195, 2008)
