Ok denk niet dat het idioom is.
Zelf bedacht waarschijnlijk.

Er wordt bedoeld dat het nationale gezag over ter wereld geldt voor de nationale personen en bedrijven.

Misschien is dit wat:

De FCPA, de Britse Bribery Act en overeenkomstige wetten hebben een lange arm, dat wil zeggen...

Nederlands idioom: de lange arm der wet

DEFINITION of Foreign Corrupt Practices Act


The Foreign Corrupt Practices Act (FCPA) is a United States law passed in 1977 that prohibits U.S. firms and individuals from paying bribes to foreign officials in furtherance of a business deal. The FCPA places no minimum amount for a punishment of a bribery payment. The Foreign Corrupt Practices Act also specifies required accounting transparency guidelines.


The act applies to actions that occur worldwide and is intended to deter corruption and abuses of power. The FCPA’s authority includes oversight of the actions of publicly traded companies as well as their directors, officers, shareholders, agents, and employees. This includes working through third parties such as consultants and partners in a joint venture with the company. That means the use of proxies to execute a bribe will not shield the company or individual from culpability.
