Academics have submitted their response to a High Court challenge over where Richard III will be laid to rest.
The remains of the Plantagenet king are due to be buried in Leicester Cathedral – the nearest church to the spot where they were found by University of Leicester archeologists last year.
However, The Plantagenet Alliance wants a judicial review of that decision.
It argues the exhumation licence issued by the Ministry of Justice, which gives the university authority to bury the king at Leicester Cathedral, should be revoked.
The group's members claim to be descendants of Richard III, the last king of the House of York, and would prefer his remains to be interred in that city.
Alliance members claim their human rights have been breached because of a lack of consultation on the decision.
The university has previously described the claim as "tosh".
It confirmed it has sent papers to the High Court.
A spokesman said: "We can confirm we have responded but we do not wish to say anything further at this time."
The Plantagenet Alliance's lawyer, Matthew Howarth, said: "I have seen a copy of what they sent. It came to me at the back end of last week. At the moment, it is too early to say anything about it."
Now all the documents have been sent to the High Court, a judge will consider them and decide whether to hear the case or dismiss it.
Mr Howarth said: "No judge has been chosen to look at it yet but when one is found, a decision will be made on an assessment on the paperwork.
"We think we have a very good case, but if the judge rejects it we have the right to get an oral hearing to persuade him it should still go ahead.
"That is not an unusual thing to happen."
It is understood the university is hoping no judge will be swayed to hear the Plantagenet Alliance's case.
Mr Howarth said he thought it would be about mid-July when the parties would have the decision.
That way, a potentially long and costly legal struggle would be avoided and the current interment plans would be unaffected.
York Minster has already stated it is happy for the king to be buried in Leicester Cathedral.
Both the cathedral and the minster have been named as interested parties in the case but church officials in Leicester said they were hoping to stay out of the matter, which they described as a distraction.
Following the announcement this year of the legal challenge, Richard Taylor, deputy registrar at the University of Leicester, tweeted: "I've been measured in my comments on the reinterment of Richard III, but the argument a Leicester reinterment breaches human rights is tosh."
City mayor Sir Peter Soulsby said at the time: "They stand no chance whatsoever.
"It's one of the most absurd claims I've heard of from an organisation I've never heard of."
