Daw’r Cod diwygiedig i rym ar 1 Tachwedd 2018 a bydd yn weithredol yn syth. Fodd bynnag, i sicrhau bod cynigwyr yn gallu cydymffurfio â’r Cod mewn perthynas ag ymgynghoriad, lle mae dogfen ymgynghori wedi’i chyhoeddi cyn y dyddiad dod i rym, sef 1 Tachwedd 2018, rhaid i gynigion gael eu cyhoeddi a’u pennu yn unol ag argraffiad cyntaf y Cod.
The revised Code comes into force on 1 November 2018 and comes into effect immediately. However to ensure that proposers are able to comply with the Code in respect of consultation, where a consultation document has been published prior to the coming into force date of 1 November 2018, proposals must be published and determined in accordance with the first edition of the Code.
