Here's an opinion that addresses how you calculate interest on various post-judgment cost and fee awards. It's rendered in 2013.
The underlying lawsuit involved a property dispute, which then devolved into multiple competing malicious prosecution actions, anti-SLAPP motions, cost and fee awards, and various enforcement proceedings. The original fee award was for around $25,000. How long could the resulting disputes really take?
Let me answer that question this way: The original lawsuit was filed in the twentieth century.
Suffice it to say that the parties don't like each other. And are affirmatively interested in battling over pittances.
