Uber told regulators Friday it would not provide names and contact information for sexual assault victims, arguing that an order filed last year violates the privacy and agency of victims who haven’t given their consent.

The company said in a filing with the California Public Utilities Commission, which regulates Uber and Lyft in the state, that sharing information “is unconscionable, actively harms the public interest, and risks retraumatizing victims in various stages of healing.” Uber said it was being singled out among the ride-hailing industry and asked the commission to revoke its ruling.

A safety report Uber released in December said more than 3,000 sexual assaults were reported during its 1.3 billion U.S. rides in 2018, including 235 rapes. In 2017, 2,936 sexual assaults, including 229 rapes, were reported in 1 billion U.S. trips.

After Uber released its report, Robert Mason, an administrative law judge with the commission, asked the company in a Dec. 19 order to provide information on when and where incidents happened and contacts for sexual assault witnesses, who in these cases are often the victims. Mason also requested more information on the company’s safety protocols and training.

Christopher Chow, a commission spokesman, said in an email that providing information allows staff to conduct follow-up investigations. Chow said the information could be filed under seal to protect privacy.

Uber’s Friday filing said disclosure could deter victims from reporting complaints they didn’t want to become public, and harm those accused of acts they didn’t commit, since the company’s reports don’t take a position on whether a reported incident actually occurred. The company also said the request contradicted state codes that require law enforcement agencies to document in writing that a victim making a report of a sexual offense may request that their name not become a matter of public record.

Allison Randall, vice president for policy and emerging issues at the National Network to End Domestic Violence in Washington, said releasing information about victims of sexual violence can place them in danger.

“It takes away their voice, their story, and that winds up having a chilling effect and causing other survivors to not come forward,” she said.

Because 1 in 3 women experience sexual assault, Randall said, she wasn’t surprised by the numbers in Uber’s report, but “every sexual assault is one too many,” she said.

Randall has been consulting with Uber since 2014; she is paid a small fee to serve on its safety board. She said she’s been impressed with changes to addressing sexual assault on the service’s rides. As outlined in Uber’s safety report, the company formed a response unit in 2017 that makes it easier to report complaints, contact 911 and reach a national domestic-violence hotline. After a complaint, Uber immediately removes the accused offender — driver or passenger — from its service and investigates whether further action is necessary, such as permanently banning the individual.

Randall said the confidentiality a survivor expects when the individual reaches out to Uber to report an incident should be maintained and the person should choose whether to report to law enforcement or any other regulators.

Some do: On Thursday, a woman in Portland sued Uber and one its drivers, alleging he sexually assaulted her in 2018 and seeking more than $1 million in damages. Uber declined to comment on the case, citing the ongoing litigation.
