The group, Europe v. Facebook, has led a campaign calling for more transparency in how Facebook handles data and alleges the social-networking site does not comply with European privacy and data handling regulations. They plan to the European Commission in Brussels.

Europe v. Facebook contends the Irish DPC, which in December analyzing Facebook's privacy and data handling practices, is not properly enforcing data regulations and that Facebook isn't complying.

"We are curious if the European Commission will take on the case," the group said in a news release.

In its , the Irish DPC made more than a dozen recommendations to Facebook on how it could improve its privacy protections and data handling. The social networking site agreed with most of the recommendations.

Facebook was supposed to implement some changes by end of last month and others later this year. The Irish DPC is scheduled to review Facebook's efforts in July.
