14 May - The Exiles insist they will pass the RFU's eligibility test to play in the Premiership if they win promotion.
16 May - They announce plans to play at Oxford United's Kassam Stadium if they go up.
23 May - RFU deems that London Welsh will not be eligible for promotion after failing to meet their Minimum Standards Criteria (MSC). That does not prevent the Exiles beating Cornish Pirates 37-21 in the first leg of the Championship final in Cornwall.
24 May - Exiles chairman Bleddyn Phillips says they are considering taking legal action to allow them to play in the Premiership.
30 May - Welsh beat Pirates 29-20 in the second leg of the Championship final to secure a 66-41 aggregate victory.
31 May - Phillips confirms that the club will appeal against the RFU's decision to deny them promotion.
19 June - Exiles learn that their appeal hearing has been put back to 28 June.
29 June - Appeal panel rules that the RFU's MSC contravenes EU and UK competition law and finds in favour of Welsh, who will play in the Premiership at Newcastle's expense.
The club then announced it would
appeal against the RFU's ruling
that stipulated that Welsh had not qualified for promotion because they did not have primacy of tenure at Oxford's Kassam Stadium - where they intend to play their home fixtures.
That point was upheld by the panel, and indeed conceded by Welsh at the appeal, but the issue of competition law was decreed to be of greater significance.
The ruling prompted the RFU's chief executive officer Ian Ritchie to announce a review of how clubs are judged for promotion to the Premiership.
"We will now instigate a full review of the minimum standards criteria, working within the Professional Game Board, with the aim of ensuring all stakeholders are agreed on the process going forward," he said.
Lyn Jones joy at Welsh promotion
"The RFU considers this matter closed which will now enable all clubs to continue their planning for the 2012-13 season."
In a statement, London Welsh added: "The fundamental strength of our case was based not only on overwhelming legal merits, including in particular anti-competition grounds, but also on the fairness and justice of rewarding through promotion the team winning on the pitch."
"It is therefore not only a victory for London Welsh, its players, coaching staff and all its supporters but also for sport in general and the game of rugby union in particular."
Exiles chairman Bleddyn Phillips was delighted with the result and was positive about sharing the Kassam Stadium next season.
"Obviously we're delighted at the result by the appeal panel and we're very much looking forward to playing Premiership rugby," he told
"We have a very good relationship with Oxford United. I think that if there are two professional teams who want to and are willing to work together, then we will be able to very amicably resolve our plans for next season.
Newcastle argued delays in making arrangements to play in Oxford should prevent London Welsh from being promoted but the independent panel of James Dingemans QC, Ian Mill QC and Tim Ward QC rejected this argument.
Falcons also released a statement following the verdict which said: "We are extremely disappointed with the decision and the representations witnessed at the appeal hearing and we will leave our options open as to where we go from here.
"We do not underestimate the competitiveness and challenges we face in the Championship but under the tutelage of Dean Richards we will have one, and only one goal - to win.
"Dean has been in this situation with Harlequins and he understands what it takes to navigate through the Championship, whilst putting together a team that will be successful with immediate effect on our return to the Premiership."
London Welsh, who have not featured in the Premiership before, will discover who they face on the opening day of next season when the fixtures are released on Wednesday, 4 July.
