Wright steps down at Shrimps
Sir David Murray says the decision to pursue oldco Rangers over undisclosed payments to players amounted to a "witch hunt".
A commission appointed by the Scottish Premier League found there was a failure to properly disclose side-letter arrangements in relation to Employee Benefit Trusts (EBTs) under Murray's ownership.
A fine of ?250,000 was imposed on the now liquidated oldco, but the commission ruled there was no reason to strip Rangers of league titles won between 2000-2011.
A statement from Murray in response to the verdict: "The problems arising at Rangers brought no credit to Scottish football and have been a tragedy for the club and its fans. They cannot be condoned.
"Similarly, however, and as stated previously, efforts to bayonet the wounded are equally unjustified and of no benefit to the club or Scottish football.
"Despite knowledge of the existence of EBT arrangements for 10 years, the SPL has never explained why this was only raised as an issue last year.
"The imposition of an irrecoverable fine on an entity which is now in liquidation is futile and only prejudices the ability of existing creditors to recover any money.
"It is saddening that so much time, effort and money has been expended in pursuing a retrospective witch hunt against an entity in crisis, as opposed to seeking to promote and further Scottish football for the benefit of the game and country as a whole."
The midfielder was given his marching orders during the first half of Town's 2-1 home defeat to Doncaster for a challenge on Iain Hume, with the score goalless at the time.
Manager Graham Turner immediately expressed his anger at the decision post match and vowed to appeal the red card and consequent suspension.
And that appeal has been successful, with McAllister free to face Walsall at the Banks's Stadium this weekend.
Turner told the club's official website: "You just feel a little bit bitter towards the referee (Oliver Langford) as the decision may well have cost us a point, perhaps even three.
"It was an absolutely shocking decision, but fortunately justice has prevailed."
Wright cited changes in the nature of his role along with a desire to spend more time with his family as reasons behind his decision.
Wright and Lord Solicitors, where Wright is a senior partner, will continue their sponsorship agreement with Morecambe, which includes the main hospitality suit at the Globe Arena.
"During my time with the club, it has gone from the Conference to the Football League and from Christie Park to the Globe Arena," Wright told the Morecambe Visitor.
"There have been changes behind the scenes in that time. When I started the club was run by a board of volunteer non-executive directors in their spare time.
"Since then, the role of the volunteer director has reduced somewhat. As the club became majority owned by Peter McGuigan, the business operations at the Globe broadened and full-time executive directors were appointed.
"It has been very time-consuming and I need to make time for other important aspects of my life. I am part of a happily growing business and a happily growing family.
"Wright and Lord have been major sponsors of the club since 2004 and that is set to continue. The firm is committed to supporting the club long into the future."
