Society and the legal system are constantly having to address the issue of time in various forms: amnesty or imprescriptibility, emergency measures or long-term solutions, acquired rights or retroactive laws, respect of precedents or reversals in jurisprudence. How can stability and change be balanced? How can the collective memory be forged while discarding a traumatic or obsolete past? How can rules be laid down for the future, while retaining the flexibility to revise them when necessary? Time is money, says the popular adage. Le Temps du Droit argues, on the contrary, that time is meaning and significance, and that it needs to be instituted rather than earned.
