Professor Solum is getting some play in the legal blogs over the last day or so. Professor Solum explains the interpretation-construction distinction, in 8 February 2009, Legal Theory Lexicon: Interpretation and Construction, post.
* Interpretation: The activity of determining the linguistic meaning (or semantic content) of a legal text.
* Construction: The activity of translating the semantic content of a legal text into legal rules.
Prof. Solum's "dictionary" is Legal Theory Lexicon.
Randy Barnett talks of Prof. Solum on usually entertaining Volokh Conspiracy blog, 8 February 2009.
