Alien

I remember during my university life when my friends and I were having this academic discussion. One of my friends actually said 'the natural rule of justice' when what he meant (and what it was supposed to be) was 'the rule of natural justice' instead.

Another friend, on the same topic, actually said 'nemo judex injuria' instead of 'nemo judex in causa sua'. Nemo judex in causa sua means 'no man can be a judge of his own cause' so our guess was that nemo judex injuria must have meant 'no man can be a judge if he's injured'.

Of course we had a good laugh then.
