DY,
1. Take an Aramaic course. Dina d’malchuta dina means that secular law is Halacha.
2. I was commenting on your use of the term “technical level”. Being that you brought it up, wouldy ou say that someone who did a melacha one minute after Shabbat comes in (ben hashemashot may be part of erev Shabbat or may be part of Shabbat) is mechallel Shabbat on a technical level?
