FIFA has been hit by fresh turmoil after Domenico Scala quit as president of the organisation’s audit and compliance committee over fears that new powers handed to the ruling Council could “impede” future corruption investigations.

The FIFA Congress in Mexico City voted on Friday to hand the Council, which replaces the executive committee, the power to appoint and dismiss members of the independent judicial committees until the next Congress in Kuala Lumpur in 2017.

That includes the two chambers of the ethics committee which have respectively investigated and suspended a number of officials in the past year, including former president Sepp Blatter.

A package of reforms voted on in Zurich on February 26 included a motion to ensure that in future the judicial committees would be completely independent of the Council in order for them to investigate and punish wrongdoing without fear or favour.

However, the decision appears to compromise the committees’ ability to fulfil their duties independently, at least until next year, and it has now led to Swiss-Italian businessman Scala tendering his resignation.
