Although academics from the University of Leuven said the changes were not dramatic, they confirmed Facebook has been acting in violation of European law for sometime.
The complaint referred to how data is gathered about people, what is done with that data once it has been collected and how people are informed of these practices.
It continued to explain the social network's settings were too complicated, meaning people could not make an informed choice about how to change their privacy and did not realise they may be surrendering data they wanted to keep private.
The group said Facebook needs to be clearer about presenting information regarding privacy, and allow users to easily obtain insights into how their data is being used by the company.
"This includes information about the websites and apps you visit, your use of our Services on those websites and apps, as well as information the developer or publisher of the app or website provides to you or us," it says.
A spokeswoman for Bart Tommelein, Belgium's state secretary for privacy, said the new laws "flagrantly go against general privacy laws in Europe. These are several things that really go too far, we think, and the task force will investigate them," she continued.
