Bydd newidiadau i'r rheoliadau heddiw yn darparu hefyd o 26 Ebrill ymlaen ar gyfer esgus rhesymol i brotestio ar lefelau rhybudd un, dau a thri, ond bydd gofyn i brotestiadau gael eu trefnu gan gorff cyfrifol a fydd yn cyflwyno mesurau lliniaru priodol, gan gynnwys cynnal asesiad risg.
Changes to the regulations today will also provide from 26 April for a reasonable excuse to protest at alert levels 1, 2 and 3, but require protests to be organised by a responsible body with appropriate mitigations, including undertaking a risk assessment.
