The documents are said to come from a case filed in California against Facebook by the application developer Six4Three, the same company from which the British Parliament seized documents in November last year.
The Guardian reported on Sunday that the leaked files showed Facebook was involved in lobbying lawmakers and regulators in the US, Canada, India, Vietnam, Brazil, Argentina, Malaysia and the EU.
No link was mentioned between the documents seized in November and the current crop. Britain's culture, media and sport committee chairman Damian Collins was at the heart of the move to seize the documents in November.
He refused to do so and was promptly escorted to Parliament where it was made plain to him that he would be fined or even jailed if he did not hand over the documents.
In Sunday's report, it was claimed that the documents showed Facebook tried to head off overly restrictive clauses in the General Data Protection Regulation that came into force in May last year.
It was also said to have used the memoir written by its chief operating officer Sheryl Sandberg - a book titled Lean In - to establish itself on a friendly footing with women who were part of the European Commission and whom it found to be unsympathetic to its cause.
But the most damaging fact was that Facebook threatened not to invest in countries which did not have laws that allowed it to do what it wanted.
Among the European officials accused of being lobbied was the former Irish Prime Minister Enda Kenny, who was described as a friend of the company.
Contacted for comment, a Facebook spokesperson said: “Like the other documents that were cherrypicked and released in violation of a court order last year, these by design tell one side of a story and omit important context.
"As we’ve said, these selective leaks came from a lawsuit where Six4Three, the creators of an app known as Pikinis, hoped to force Facebook to share information on friends of the app’s users. These documents have been sealed by a Californian court so we're not able to discuss them in detail.”
