Canon 26 is one of the six canons (24-29) attributed to the First Council of Arles which are transmitted by only two codices (Parisiensis Lat. 12448 and Bodl. 893). Compare with canon 6 of the Council Thelense (North Africa, AD 418), see [274].
This canon forbids clerics to be ordained in a church other than the one in which they were ordained for the first time. Hence, this canon does not apply to lay people.
