General question about decisions Forum

[Younks]

I have a quick question that a law student would be uniquely qualified to answer in order to test a hypothesis, (which I will share after receiving a few answers in order to keep the responses unbiased).

In my limited undergraduate readings of court cases, it seems that at some point in time the language used in these cases became far less ornate. For example, British commonlaw cases are generally wordier/require a much larger vocabulary than more recent decisions.

My question is: what year/decade/time period in general would you say the cases started to sound more like an 'average' citizen's speech?

Would you agree with that generalization?
