CUSTUMAL: CAPITULUM 27

In a plea of debt between a peer of the city and a foreigner, whether initiated by or without king's writ, when it comes to judgement the peer's proof is to hold good over the word of a foreigner. The citizen may wage his law according to the ancient customs of the city.

[In the absence of any deciding factor, when it came down to word against word, it was natural enough that the city court would show favouritism to citizens.]
