I think this has manifested at its peak with Ethereum.
>evolution of the law (which involves creating new portions of the law to cover previously created portions which are considered lacking)
And argue that electronic privacy vis-a-vis wiretapping laws is creating a new portion of the law to cover previously created portions which are considered lacking. We can quibble about definitions, but that strikes me as very much in the area of "evolution".
In common law systems it is precisely their job to do so.
The reality in Common Law legal systems is nothing like this, and judge made law through interpretation and application of precedent is a very real thing, even in the USA. As a particularly blunt example, in some parts of the UK such as Scotland, the traditional common law crimes such as murder/theft etc aren't even defined in primary legislation ("laws"), and exist solely as judge made and applied creations through decades of precedent. Even where there exists primary legislation, the scope of judicial interpretation gives a great deal of freedom to judges to establish precedents that the drafters might not have foreseen or intended.
Heck even the definition of the term "Common Law" is normally interpreted to mean "Case Law" as developed by judges.
Also, as I've seen in other comments, we're going to get on the merry-go-round of defining "create law".
