The investigation into the two million Swiss franc payment from Fifa to UEFA president Platini in 2011 form part of a broader corruption scandal shaking the world football body.
The pair were provisionally banned for 90 days by Fifa on 8 October, pending the full investigation by Fifa’s Ethics investigators which concluded on Friday. The body could, if they deemed it suitable, impose a further ban on one or both.
Blatter also faces a Swiss criminal investigation over the matter.
“The adjudicatory chamber of the independent Ethics Committee...has today opened formal adjudicatory proceedings against Joseph S. Blatter and Michel Platini based on the final reports submitted by the investigatory chamber,” said a statement from Eckert’s spokesman.
