This Practice Note sets out ways in which in-house lawyers can work effectively with other functions within the business to ensure compliance with regulatory requirements. What regulations need to be complied with and who is responsible for compliance programmes? In any organisation there will be sector‑specific rules and cross‑cutting obligations (for example data protection, health and safety, competition, product safety, financial crime, environmental obligations, employment, consumer protection, advertising and marketing, sanctions/export controls, and reporting/tax). In an organisation which is in a regulated sector, the presence of the compliance department should be obvious. However it is rare that a compliance department covers every type of regulation. When the main business activity is not regulated, the way in which compliance is tackled may be fragmented. Someone in the human resources (HR) department may lead on health and safety. Someone else in HR may lead on ethics (anti-bribery). There may be an environment team leading on environmental regulations but perhaps they don't cover some issues, eg how products should be packaged
