It's understood City's second challenge against the Premier League's Associated Party Transaction (APT) rules will go to trial in October.
The rules regulate sponsorship deals which clubs sign with companies linked to their owners.
The Premier League champions initially challenged the league over the rules in January 2024.
A judgement was handed down earlier this year finding that all the rules must be void.
City still believe the rewritten APT rules are anti-competitive and breach public law principles.
