Ym mis Mai 2019, cyflwynais Ddatganiad Ysgrifenedig ynglŷn â lefel yr isafbris uned a ffefrir, sef 50c, gan nodi ein bwriad i osod y Rheoliadau hyn. Gwnaethom gyfeirio'r Rheoliadau drafft at Gomisiwn yr UE yn unol â'r Gyfarwyddeb Safonau a Rheoliadau Technegol 2015/1535/UE, ac yn dilyn hyn cafwyd cyfnod segur o dri mis pan nad oedd Llywodraeth Cymru yn gallu gosod y rheoliadau drafft.
In May 2019, I issued a Written Statement about our consultation on the preferred level of a 50p MUP, noting our intention to lay these Regulations. We referred the draft Regulations to the EU Commission in accordance with the Technical Standards and Regulations Directive 2015/1535/EU, which was followed by a three-month standstill period, during which the Welsh Government could not lay the draft regulations.
