How long will my case take?

Nathan here. I'm back for a guest post with some new tricks I've learned at my new job from some of the researchers at UAMS. I've having a blast getting an inside look at cutting-edge biomedical research. This post looks at some data visualization about the time it takes to resolve civil tort cases in Arkansas.


One of the researchers has a master's degree in computer science, and I picked his brain a little bit about what software packages he likes to use. He prefers python to Perl (which I like) because python's research libraries are easier to use.

I took his recommendations to heart, and I've been tinkering around with the Anaconda python distribution with data I've gathered for another project I'm working on releasing very soon: Docket Dog. It's an Arkansas state court notification system. I used the data mining application Orange to perform some data visualization on the types of civil cases my dad and brother handle.

Arkansas Tort Case Length Analysis:

I took a look at over 98000 tort cases available electronically from the Administrative Office of the Courts for which I could calculate an end date. This is what the time frames look like:

As you can see, civil court cases can take several years to resolve. We'll see what the averages look like here in a few minutes with another chart.

In the meantime, there are several interesting patterns that appear in this chart. For instance, on the first line for product liability cases, there are several vertical bands around 9, 12, and 14–16 years. I haven't looked into this, but I suspect each band probably represents a settlement of a specific type of cases, like Firestone exploding tire cases, Pinto exploding car cases, or something similar.

The declaratory judgment (dec action) line is notably shorter overall than the others. Again, I haven't researched this further, but I would expect this is due to the fact that dec actions don't involve juries and are usually about a specific question of law. For instance, lots of dec actions involve whether there is insurance coverage for a particular event or not (the hilarious Luther Sutter v. Dennis Milligan dec action notwithstanding). 

Now, on to the next chart. This is called a box chart:

This chart is broken up into quartiles. The light blue box represents 50% of all cases. So, 50% of motor vehicle collision (MVC) cases are decided within 2 years, with the median value being 1.6 years. (Median means the middle value; if there were 101 cases, for instance, the median value would be the 51st value). The average MVC case length is shorter at just over 1 year.

The dark blue lines represent maximum values, excluding outliers. The dots out to the right of the graph represent those outliers, which extend out to 20 years.

What's the bottom line? For 3/4 of tort cases, you can expect resolution to take at least 6 months to 3 years. Another quarter of cases take up to 4 years or so. And, there are always outliers that can take many, many years to reach ultimate resolution.

What questions do you have about this analysis?
