A lawyer representing relatives of Abdelbaset al-Megrahi said he is sending three volumes of papers as part of the appeal against the Libyan's conviction for the Lockerbie bombing.
Speaking at a press conference in Glasgow, Aamer Anwar said the documents would now be delivered to the Scottish Criminal Cases Review Commission for consideration, according to reports from STV.
The appeal is backed by long-time campaigner Dr Jim Swire and 23 other British relatives of victims of the bombing, along with six members of Mr Megrahi's family, who are not being identified for safety reasons.
ITN Scotland correspondent Debi Edward is at the press conference announcing an appeal against the conviction of Abdelbaset al-Megrahi for the 1988 Lockerbie bombing.
Mr Megrahi's family say they are seeking justice for the victims of the atrocity, as well as for Mr Megrahi himself.

Lawyers are trying to relaunch an appeal that Mr Megrahi had prepared prior to his release from jail in 2009 on compassionate grounds.
Relatives of Abdelbaset al-Megrahi, the only man convicted of the 1988 Lockerbie bombing, have launched an appeal to posthumously clear his name.
Mr Megrahi was convicted of the bombing but released from a Scottish prison in 2009 on compassionate grounds as he had cancer. He later died in Libya in 2012.
Lawyer Aamer Anwar announced the appeal at a press conference alongside Dr Jim Swire, whose daughter Flora died in the atrocity and who has campaigned for the case to be re-opened.
A new application has been made to review the conviction of the Lockerbie bomber.
Dr Jim Swire, whose daughter was killed in the 1988 disaster, has put in a formal request to the Scottish Criminal Cases Review Commission.
Libyan Abdelbaset al-Megrahi was found guilty of murder in 2001. He has since died after being released from prison on compassionate grounds.
Fiona McIlwraith reports:
A new application to review the conviction of the Lockerbie bomber will be made to the Scottish Criminal Cases Review Commission.
Dr Jim Swire, whose daughter Flora was killed in the 1988 disaster, has made the request on behalf of himself and others.
Libyan Abdelbaset Al-Megrahi was convicted in 2001 of the murder of the 259 passengers and crew on board Pan Am flight 103, and 11 residents of Lockerbie.
He died three years after being released from prison on compassionate grounds.
John Gair witnessed the disaster and has welcomed the calls for a review:
It's now 14 years since Abdelbaset al-Megrahi was found guilty in 2001, for blowing up Pan Am flight 103 over Lockerbie.
270 people were killed in the bombing on 21 December 1988.
This is the third attempt to appeal Megrahi's conviction and Jim Swire is behind the campaign.
“After I realised that he had nothing to do with the murder of my daughter, Megrahi became my friend. There are a lot of legal people in Scotland who want to see this issue properly resolved.
"I hope that the appeal will succeed and, when it does, Megrahi’s family will no longer be regarded as the family of the so-called Lockerbie bomber.”
A fresh appeal could begin into whether the Lockerbie bomber was wrongly convicted.
Libyan Abdelbaset al-Megrahi was found guilty of blowing up Pan Am Flight 103 over the town in 1988.
He was released from prison in 2009 after abandoning a second appeal against his conviction and died three years later.
Dr Jim Swire, whose daughter Flora died on the plane, believes he was innocent and is asking for permission to continue the legal appeal on Megrahi's behalf.
The people of Lockerbie came out to welcome the medal-winning curling teams from Team GB, as they paraded though the town.
The men's and women's Winter Olympic teams were given a civic reception in honour of their achievements in Sochi earlier this year.
Fiona McIlwraith was there:
Both Team GB's men and women curlers were welcomed to Lockerbie today with a range of events.
The day started off with a Q&A session with local children, before the teams were piped through the streets of the town.
Huge crowds came out to meet them.
"It's incredible, I've been looking forward to this for such a long time and to come and see all the people that gave us such good support and knowing that this was all hear for us ready and waiting, it so so special."
"It's fantastic. It's actually the first time I've been back to the town, there's still a lot of people that I haven't seen yet that I would like to so yeah I'm looking forward to the rest of the day."
A civic reception is being held in Lockerbie for Team GB's Winter Olympic curlers.
