I have to write in AP Style.
The judge ordered a suspended sentence for the convicted felon and said the parole would stand as long as Jones followed the guidelines for good behavior.
Any public relations professional must al least consider a set of ethical principals before deciding to pursue a questionable campaign.
Neither they nor he are going.
I'm not familiar with AP style specifically, so please use these guides to help.

Just reading these sentences, though, I'd say the first one is wordy and needs to be cut into two sentences; the second is too wordy; in the third, I'd reverse "they" and "he" but keep the rest the same.
