This section applies where a commitments decision has effect in relation to a person who provides a public electronic communications network ("the dominant provider").
The dominant provider may notify OFCOM of a proposed modification of the commitments that are made binding by the commitments decision.
In a case where OFCOM consider that the modification would not have a material effect, they may make a decision under section 93A(8) relating to the commitments as proposed to be modified.
In any other case, OFCOM must notify the dominant provider of their opinion that the proposed modification would have a material effect; and subsections (2) to (10) of section 93A then apply in relation to the commitments as proposed to be modified.
