The case offers two enduring lessons. The first is that those who think about suing for libel should think again before doing so. And then again once more. While all the ultimate consequences to the Islamic Society for bringing the lawsuit remain uncertain, any adverse consequences could have been avoided by not suing in the first place.
The second lesson is that in one way (and perhaps no other) we should learn from the English system and award counsel fees to the winning side in cases like this, which are brought to inhibit speech on matters of serious public import. Because all the defendants in this case were steadfast and refused to settle, they were eventually vindicated. But the real way to avoid meritless cases such as this is to have a body of law that makes clear that plaintiffs who bring them will be held financially responsible for doing so.
