Be that as it may, Damian Collins, executive of the Commons Digital, Culture, Media and Sport (DCMS) Committee, said he trusts the records - which incorporate messages - contain critical data about how Facebook and different gatherings handle client information.
In a highly unusual move a serjeant at arms was sent to the businessman's hotel and he was given a final warning and a two-hour deadline to comply with the order.
Collins' seizure, however, did not take place against Facebook itself; rather, the documents have been seized from U.S. software development company Six4Three after having been obtained as part of the discovery process in a lawsuit against Facebook.
According to the Guardian, the documents were initially obtained during a legal discovery process by the now-defunct US software company Six4Three, which is currently suing Facebook.
It's suing Facebook over a change to the social network's privacy policies in 2015 that led to the company having to shut down its app, Pikinis, which let users find photos of their friends in bikinis and bathing suits by searching their friends list.
The app maker, Six4Three, had acquired the files as part of a USA lawsuit against the social media giant.
"We are in uncharted territory".
But Mr Collins seems convinced they will prove relevant to the DCMS committee's inquiry into how another developer - Dr Aleksandr Kogan - was allowed to get access to data he handed to Cambridge Analytica.
Allan pleaded with Collins not to raise the material at the hearing, which MPs are entitled to do under Parliamentary privilege, "until we have further guidance from the court".
Allan was responding to Canadian lawmaker Charlie Angus, who said the social media giant has "lost the trust of the worldwide community to self-police", and that governments have to start looking at ways to hold the company accountable.
