I don't think boards should be mandated to use language. Although our mother tongue is Pidgin, writing in English seems easier to us...
This my post is off-topic but I think it is worth correcting this. Pidgin is not our mothers' tongue. Mother's languages are local languages. Pidgin is derived from English and native languages in a way people that are not educated can also easily be able to speak and write English which led to Pidgin.
Yes, Pidgin is not our mother's language. Our native language is what we call our mothers tongue and it is our first and primary language. I still see a few people who are unable to speak pidgin same with those able to speake pidgin alone and aswell even the better population knows how to speak both. Reading the rules and regulations of the local board, English and pidgin are acceptable so everyone has the right to pick between both to speak, sometimes depending on one's state of mind the person might decide to speak differently with pidgin or sometimes proper English.
