Comprehensive Computer Data Access and Fraud Act (knowing access without permission)

Cal. Penal Code § 502

In force.

A computer misuse rule binding public and private bodies.

Audit expectation
none

What it requires

  • Do not continue accessing a California site, or circumvent a technical block, after the operator has sent a cease-and-desist notice (Facebook v. Power Ventures, 9th Cir. 2016; Craigslist v. 3Taps, N.D. Cal. 2013).
  • Note that this statute's without permission standard has no threshold requirement that your initial access be unauthorized, unlike the federal Computer Fraud and Abuse Act (CFAA).

These lines are LexLint's reading of the law's text. Also read by: Facebook, Inc. v. Power Ventures, Inc., 844 F.3d 1058 (9th Cir. 2016) (recorded ).

Case citation
Facebook, Inc. v. Power Ventures, Inc., 844 F.3d 1058 (9th Cir. 2016)
Open questions
  • Does a scraper act "without permission" under Penal Code section 502(c)(2) when the operator has imposed only a technical block, such as an IP block, and has sent no cease and desist letter?
  • Does a scraper that copies data from a publicly accessible page act "without permission" under Penal Code section 502(c)(2) because the operator's terms of use prohibit automated collection?

What it makes you log

Logging duty

Section 502(c) lists the public offences of knowing access without permission, from altering or deleting data to taking, copying or using it, subdivision (e) gives the owner a civil action and subdivision (d) sets the punishments. Nothing in the section requires anyone to create, keep, produce or review a log or record; the word record appears only in the definition of a computer contaminant. Subdivision (j) treats a person who accesses a computer in one jurisdiction from another as having accessed it in each, which turns on where the computer is and names no territorial hook.

Section 502(c) criminalizes knowing access without permission, and the Ninth Circuit has said the statute is different from the federal Computer Fraud and Abuse Act (CFAA) because it does not require unauthorized access and merely requires knowing access. Facebook v. Power Ventures (844 F.3d 1058, 9th Cir. 2016) held a scraper's originally-permitted access did not violate this section, but access became without permission once Facebook sent a cease-and-desist and IP-blocked the scraper and it continued anyway.

Craigslist v. 3Taps (964 F. Supp. 2d 1178, N.D. Cal. 2013) denied a motion to dismiss CFAA and section 502 claims against a scraper alleged to have kept scraping after a personally addressed cease-and-desist letter and an IP block. The court reasoned that a person of ordinary intelligence would understand those actions as a revocation of authorization to access the website. The current section was added by chapter 1499 of the Statutes of 1987.

The section's history note records only its most recent amendment, and no day on which chapter 1499 came into force has been located.
