Couple of other silly things from the past are still prevalent.
- The whole concept of a summer vacation is rubbish. Why on earth should the highest court in the land go on holiday? Does that mean that justice is ignored for that time? I would think that the system came into place during the British Raj, when most judges were British. Given the difference in climate between the UK and India, it made sense to have a summer holiday to escape the heat, esp. if you weren't used to it. In modern times, this makes no sense. The summer holidays can be seen here.
- Blacks Robes are next on the list. Why do we need them? I agree that there is no way that you would trust a lawyer or a doctor who is not dress formally. So, let the lawyers be allowed to just dress in formal clothes. A Coat and Tie should suffice. link.
