CAS offered no further details but the AP reported on Wednesday that City is challenging the legitimacy and haste of the investigation. The UEFA investigation was sparked by leaks of City's internal correspondence and documents to German outlet Der Spiegel.
The leaks implied City deceived UEFA for several years, including by hiding that revenue from potentially overvalued commercial deals came from the club's owners in Abu Dhabi to curb losses. City hasn't disputed the authenticity of the documents.
