California resident and serial plaintiff Jerry Aviles has sued RELX Inc., the parent company of LexisNexis and Lex Machina, alleging that it deployed web tracking software on its Lex Machina website without users’ prior consent, in violation of the California Invasion of Privacy Act (CIPA).

CIPA, passed in 1967, protects against eavesdropping and wiretrapping, specifically targeting pen registers and “trap and trace” (PR/TT) devices that record outgoing and incoming information, respectively.
