This is from a style guide on a Canadian government site, so it's possible it only applies to Canada. But I'm in Canada, so that's fine.
Collective nouns such as board, cabinet, commission, committee, council, government, group, majority, number, and series take their verb or pronoun in either the singular or plural, depending upon the context in which they are used. Use the plural when the action is taken by the individual members considered in their separate capacities, and use the singular when the group acts or thinks as a whole:
The committee have discussed all aspects of the case and have not yet reached agreement.
The committee approved the motion unanimously and directed its subcommittee to take immediate action.
