asking as a favor against Paul that he summon him to Jerusalem—because they were planning an ambush to kill him on the way.
See how restless malice is: Paul bears his imprisonment patiently, yet his enemies cannot bear even a three-day delay in pursuing him to death. They rush upon Festus the moment he arrives, trying to prejudge the cause before any fair trial.

Commenting on Acts 25:1-12
And desired favour against him,.... Paul; they asked what would be a favour to them, and a prejudice to him: or "of him", that is, of Festus; they asked a favour of him, and desired it as such, as what would be gratefully accepted and acknowledged by them; which sense is confirmed by the Syriac version; the Arabic version renders it "to", or "upon them"...
Verse 3. And desired favour against him. Desired the favour of Festus, that they might accomplish their wicked purpose on Paul. Would send for him to Jerusalem. Probably under a pretence that he might be tried by the sanhedrim; or perhaps they wished Festus to hear the cause there, and to decide it while he was at Jerusalem. Their real motive is immediately stated.
