Securing a Legislative Victory for the American Car Rental Association

Lewis Rice member David W. Sweeney represented the American Car Rental Association (ACRA) in its effort to shape legislation governing the operations of Turo, an online car-sharing platform, at St. Louis Lambert International Airport. The initial bill would have permitted Turo to operate in airport garages within walking distance of passenger terminals, a proposal opposed by members of the St. Louis Airport Commission due to competitive concerns. David engaged with stakeholders to negotiate a revised agreement that addressed these objections while protecting the interests of ACRA. The final legislation limits Turo’s operations to three designated parking areas west of Terminal 1. The measure was opposed by the St Louis Airport Director but  approved unanimously by the St. Louis Board of Aldermen, marking a significant milestone in the legislative process. This outcome preserved competitive balance in the airport rental market and aligned with ACRA’s policy objectives. The case demonstrates how strategic advocacy and effective negotiation can deliver tangible results for industry associations facing complex regulatory challenges.

California Legislature Eliminates Private Right of Action for Certain Claims Under CIPA

On September 30, 2026, California Governor Gavin Newsom signed Senate Bill 690 (“SB 690”), which the California Legislature unanimously passed on August 28, 2026. The new law, which will take effect on January 1, 2027, eliminates the private right of action for online pen register and trap and trace claims under the California Invasion of Privacy Act (“CIPA”). Although SB 690 marks a substantial change to the CIPA landscape, which has been flooded with claims in recent years, it does not provide complete relief to companies that use commonplace online tracking technologies like cookies. Rather, the law shifts enforcement from private plaintiffs to the California Attorney General. Further, plaintiffs may try to challenge the same tracking technologies under other provisions of CIPA or other laws. Background CIPA was originally enacted in 1967. It prohibits any interception or recording of confidential communications of another without their consent. Broadly speaking, the law prohibits wiretapping, eavesdropping, the recording of private communications, and the use of pen registers or trap and trace devices. As relevant to SB 690, Section 638.51 of CIPA prohibits the installation or use of a pen register or trap and trace device without having first obtained a court order or consent. CIPA’s civil enforcement provision, Section 637.2, provides statutory damages of $5,000 per violation plus three times the amount of actual damages, if any, that a plaintiff sustains. Prior to the enactment of SB 690, CIPA provided individuals with a direct cause of action against any private actor for violations of the law. Over the past few years, the number of CIPA pen register and trap and trace lawsuits has exploded. Plaintiffs have used CIPA’s private right of action to threaten and/or bring thousands of claims, including class action lawsuits, against companies. By and large, these claims argue that companies violated CIPA’s prohibition on pen register and trap and trace devices through their use of common online tracking technologies, including cookies, third-party pixels, website analytics, and similar technologies. Plaintiffs typically allege that such technologies are pen registers or trap and trace devices and that companies violate Section 638.51 by using those technologies without a court order or consent. Plaintiffs in these actions seek the statutory damages of $5,000 per violation, which is the maximum amount recoverable without showing actual damages. Courts have determined that CIPA applies so long as the internet user is within California, meaning that companies based outside of California may still be subject to CIPA liability. Key Changes Effective January 1, 2027, SB 690 amends CIPA’s civil enforcement provision, resulting in two major changes.  Private plaintiffs can no longer file pen register and trap and trace claims for conduct occurring on an internet website, online application, or mobile application. Only the California Attorney General may bring such claims.  SB 690 is retroactive to January 1, 2025. Any lawsuit filed by a private plaintiff on or after January 1, 2025 that alleges an unlawful pen register or trap and trace device in connection with an internet website, online application, or mobile application will be barred. Cases filed prior to January 1, 2025 are left unaffected, as are civil enforcement claims brought by the California Attorney General. What SB 690 Has Not Changed Although the elimination of the private right of action for certain pen register and trap and trace claims is a major development that will bar many threatened and pending lawsuits, SB 690 is not a complete overhaul of CIPA.  Online pen registers and trap and trace devices are still illegal without a court order or consent. SB 690 only shifts the enforcement to the California Attorney General.  Plaintiffs still have a private right of action for wiretapping claims or eavesdropping claims. SB 690 specifies that only the California Attorney General may bring lawsuits alleging violations of Section 638.51. Private plaintiffs may still bring wiretapping claims under Section 631 or eavesdropping claims under Sections 632 and 637. These plaintiffs may still seek the $5,000 statutory damages for such violations of CIPA and may still potentially file class action lawsuits. Legislative action to curb these claims may be forthcoming. When Governor Newsom signed SB 690, he noted that “additional work in this area is needed, as CIPA contains other decades-old statutes that are also susceptible to abuse by overly aggressive litigants,” and he urged the California legislature to take this on next year to “ensure a fair balance between protection private information and preventing rapacious litigation.” Looking Forward While SB 690 is an important change, companies should remain vigilant with respect to the use of third-party tools within their websites and potential CIPA lawsuits. It is likely that plaintiffs will now allege that the same internet tracking technologies amount to wiretapping or eavesdropping violating Sections 631, 632, and 632.7 and seek the $5,000 statutory damages per putative violation, in addition to violations of other laws. Further, the California Legislature’s elimination of a private right of action for online pen register and trap and trace device cases does not eliminate the risk of suit under Section 638.51. The California Attorney General may pick up where private lawsuits have left off, though Governor Newsom stated that he is aligned with the “goal of protecting small businesses from overzealous lawsuits based on a statute written without today’s complex technological landscape in mind.” If you would like assistance with, or have any questions about, CIPA claims, please contact one of the authors of this alert.

Federal Lawsuit Filed on Behalf of Polk County, Iowa, Landowners Whose Property was Taken by the Federal Government

Lindsay S.C. Brinton and Meghan S. Largent, attorneys from Lewis Rice’s Federal Takings & Rails to Trails Practice, filed a case in the United States Court of Federal Claims on behalf of 29 landowners in Polk County, Iowa, on Aug. 7, 2026. The lawsuit alleges that the federal government owes the landowners compensation for their property that it authorized for public trail use. The federal Surface Transportation Board (STB) issued an order called a Notice of Interim Trail Use or Abandonment on July 31, 2026. This authorizes the cities of Des Moines, West Des Moines, Windsor Heights, Urbandale, Clive and Grimes to convert the abandoned 12.2-mile Norfolk Southern railway corridor known as the Grimes Line into a public hiking and biking trail. Because converting the rail line to a public trail is not authorized under Iowa law, the cities sought permission from the STB to acquire the rail line from Norfolk Southern Railway so the land could be put to public use. The STB granted that request, which gave rise to the landowners’ lawsuit. The lawsuit alleges that Norfolk Southern does not own the land underlying its rail corridor, but rather has operated the railroad across the land pursuant to century-old easements. Once the railroad is abandoned, those easements would have ceased to exist. “Pursuant to the National Trails System Act, the federal government has the constitutional authority to take these landowners’ property for conversion to a public-access recreational trail and preservation of a railroad easement,” Meghan said. “However, the Fifth Amendment to the United States Constitution requires the federal government to pay the landowners for the value of their property taken.” The lawsuit asks the Court to compensate each landowner for the fair market value of the property that will now be encumbered by the public recreational trail easement. The lawsuit is only against the federal government and makes no claims against Norfolk Southern Railway nor the cities involved in the transaction. The lawsuit does not aim to stop the transfer of the railroad property to the cities for a public trail nor does it seek to impact the funding for the proposed trail in any way. More than 200 landowners are currently eligible to make a claim for compensation. Lindsay and Meghan are continuing to add landowners to this case and plan to reach out to more along the corridor in the coming weeks. Lewis Rice's federal takings attorneys represent landowners throughout the United States pursuing takings claims against the federal government. One primary focus of the group is representing landowners in what is commonly referred to as rails to trails takings. Attorneys in this group litigate cases in the United States Court of Federal Claims on behalf of those whose property was taken by the federal government pursuant to the National Trails System Act, which authorizes abandoned railroad lines to be converted to public parks. The goal is to obtain compensation from the government for the taking of their land for the public recreational trail. The attorneys in the Federal Takings Practice Group focus on both proving the taking has occurred as well as establishing the value of the property that was taken. Their national work for landowners includes representing landowners coast-to-coast, including 11 states.
