Facebook's Zuckerberg, Sandberg won't appear before committee, could be found in contempt of Parliament

Canadian MPs are warning that Facebook's top officials could be found in contempt of Parliament if theycontinueto ignore a subpoena to testify in Ottawathis week, as company representatives confirmed Monday that Facebook founder Mark Zuckerberg and chief operating officer Sheryl Sandbergwouldnot attend.

Starting today, the House of Commons's privacy and ethics committee will be joined by elected officials from around the world to discuss data collection, privacy online and democracy and to question witnesses.

The committee had extended invitations to some of the most well-known tech players, including Facebook, Twitterand Google. Earlier this month, the committee voted to subpoenaZuckerberg andSandberg to appear as witnesses.

Kevin Chan, head of public policy for Facebook Canada, told CBC News he and Neil Potts, director of public policy for Facebook, will be answering the committee's questions instead.

Conservative MP Bob Zimmer said the ethics committee has talked about finding Zuckerbergand Sandberg in contempt of Parliament if theycontinue to ignore the committee's summons.

"I don't think it would send a good message internationally about, you know, blowing off an entire country of 36 million people," said Zimmer, the chair of the Commons committee.

"The bottom line is that they show up and answer our questions, so my hope is that still happens."

If Zuckerberg and Sandberg are no-shows this week, the committee would first have to vote on a motion recommending a contempt finding before it could go to the floor of the House of Commons for a vote.

Finding someone guilty of contempt of Parliament is a rare move in Canada.

A study by the Library of Parliament found that, while"allegations of contemptuous behaviour are made frequently, findings of contempt are unusual."

Also, while the House of Commons has a range of penalties to punish contempt, a"finding of contempt is often considered sufficient in itself," notes the library.

Symbolic messaging

Even if it's only a symbolic finding, it could send a message, said NDP MP and committee vice-chair Charlie Angus.

"If they believe that Canadian lawmakers are so inconsequential, then that is contempt of Parliament," said Angus.

"You have a company that acts with complete disregard for the democratic systems that we've put in place To me, that's just unbelievable that a company could be that dismissive. And I think they have to be held accountable."

Liberal MP Michel Picard, another committee member, said a contempt ruling would show how seriously Canada takes the issue.

"We are not hunting companies. We are demanding as much collaboration as possible," he said.

"We need those companies to work more with us."

Zimmer said the committee hopes to come up with a communiqu at the end of their three-day session to outline best practices when it comes to protecting citizens' rights in the age of big data.

No new legislation coming

The international gathering will also discuss mounting calls to break up Facebook, said Angus. It'san idea thatgained traction when Chris Hughes, who helped start Facebook with Zuckerberg, wrote an op-ed in the New York Times arguing that the $514 billion company has grown too powerful.

It's a conversation Democratic Institutions Minister Karina Gould said she'll be watching closely.

"The rest of the world is starting to think about this as well, because I'm not sure if there's been a time in history when so few companies were really responsible for so much of the activity that we do every single day, from shopping to banking to searching for information to communicating with others," she said.

Along with Canadian MPs, the grand committee is made up of politicians fromthe United Kingdom, Argentina, Belgium, Brazil, France, Ireland, Latvia, Singapore. Ecuador, Mexico, Morocco and Trinidad and Tobago.

Representatives of Facebook, Twitter, Google, Microsoft, Amazon and Apple are all slotted to appear, but so far the witness list says only,"To be determined."

Among those who have already agreed to appear at the grand committee are Jim Balsillie, former chief executive of Blackberry, Ellen Weintraub, chair of the U.S. Federal Election Commission, and Privacy Commissioner Daniel Therrien.

It'll be the second time the international coalition has met. They gathered last year in the U.K.; Zuckerberg did not show up for that gathering either.

This week's meetings come days after Ottawa laid out its digital charter, a list of principles to guide an overhaul of Canada's laws governing the internet and digital privacy.

However, Gould said no legislation is coming until after the next election.

"I think we've run out of runway with regards to legislating before the House rises in June," she said.

Last month,Therrien announced plans to take Facebook to Federal Court after finding Facebook had violated Canada's privacy law by sharing the personal information of Canadian Facebook users in the course of the Cambridge Analytica scandal.

Facebook has disputed the report's findings.

Cambridge Analytica is accused of harvesting data of more than 50 million Facebook users worldwide to create social media strategies to support U.S. President Donald Trump's 2016 election campaign.

The grand committee gathering kicks off Monday night at 7 p.m. ET.
