Germany's parliament has been ordered to release confidential documents about UFOs after a lengthy legal battle.

The existence of the files was disputed as recently as 2008, but a UFO enthusiast discovered evidence to the contrary and pushed for their release.

The German Supreme Administrative Court in Leipzig ordered the Bundestag to make the UFO files available.

In 2008, Dr Wolfgang Schäuble, Germany's Minister of the Interior denied that the German government had ever investigated UFOs, but in 2009, a UFO enthusiast named Robert Fleischer discovered a parliamentary department had been investigating extraterrestrial objects.

A German blogger named Frank Reitemeyer took the Bundestag to court over the secret reports and the dispute has only just been resolved,The Express reported.

No date for the release of information has yet been confirmed.

Nigel Watson, author of the UFO Investigation Manual, said: 'They won't reveal any secrets about hidden alien technology or alien bodies, but then again we can always hope!'

Mr Watson believes some governments hide UFO-related information to protect other secrets.

'Sometimes governments hide information like this to protect operational procedures or protect non-UFO related secrets, like the capabilities of early warning systems or the names and details of witnesses,' he said.

'In this case perhaps they don't want to show they have taken this subject seriously, or that they are as much in the dark as everyone else.'

It was only in 2005 that the British government admitted conducting a thorough scientific study into UFOs, after years of denial.

'It concluded that unidentified aerial phenomena, or UAPs, do exist, but not flying saucers,' Mr Watson said.

'When, or if the German files are released, it will be interesting to see if they come to similar conclusions.'
