Yeah. A good illustration of why the ambulatory approach is important. Another eg from an actual case in the 1970s in the uk: 19th C statute regulated hansom cabs. Motor cabs did not exist when statute was passed. Court had no issue saying the law applied to cars. ACT would make that impossible.
What do you mean the ban on death threats passed in the Crimes Act 1961 includes death threats sent by email? Don't be ridiculous. If you Parliament wants to ban emailed death threats, it will amend the law. Until then, not covered.
