Mae’r Bil hefyd yn darparu pŵer wrth gefn i ohirio’r etholiad am hyd at 6 mis, os bydd cyffredinrwydd y feirws yn agosach at yr amser yn golygu na ellid cynnal yr etholiad yn ddiogel. Dim ond os bydd dwy ran o dair o holl Aelodau’r Senedd yn cytuno y gellir gwneud penderfyniad o’r fath – byddai pob Aelod yn cael chwarae ei ran yn y penderfyniad terfynol felly.
The Bill also provides a contingency power for the election to be postponed for up to 6 months, if the prevalence of the virus closer to the time means the election could not be conducted safely and securely. Such a decision could only be taken with the agreement of two-thirds of Members of the Senedd, which means all Members would have a role in the final decision.
