The defender was set to be denied the chance to feature in Inverness' first appearance in the Scottish Cup final after being retrospectively punished for deliberately handling a Leigh Griffiths header in last weekend's 3-2 semi-final victory over Scottish champions Celtic.
However, Inverness challenged the decision and a tribunal met on Thursday and reversed the ruling, meaning he is free to play in the showpiece against Falkirk on May 30.
A statement from club chairman Kenny Cameron on Inverness' official website read: "The result means that the club can now fully appreciate the achievement of reaching its first ever Scottish Cup final and focus on preparations for Saturday's [Scottish Premiership] game versus Aberdeen."
Meekings received widespread support, with FIFA's referee chief Jim Boyce stating that a ban would set a "very dangerous precedent", while former Celtic boss Neil Lennon said the decision would "open up a can of worms".
