Do you think it might be possible to eventually use a Deep Learning model like GPT-3 to do the formalisation for us? It seems like a herculean task to do it by hand.
Short/mid term I believe that we will have tool allowing lawyer / regulator to draft in a formal form from which we will derive the legaleese. The stanford LSP is pushing in this direction and there is early tentative tools already published such as blawx or Oracle Policy Automation. I m aware of at least 3 other tool under development that push for this paradigm.
Fun fact one of the earliest effort in computational law involve lawyer writing contract in a formal english in ~1957 (original paper still full of good ideas on legal formalism https://digitalcommons.law.yale.edu/cgi/viewcont )
constitutional :: Constitution -> (Law | Reform) -> Boolean
I really would like to see if one can train a model like that. seeing what gpt-3 can do, it seems that we are not that far away to achieve something like an AI lawyer.
