are the laws that underwrote the british anti-piracy and anti-slavery activities of the West Africa Squadron and other Royal Navy units still in effect and if not are there similar laws that would justify similar actions in the present day
The specific 19th-century British laws—such as the
Slave Trade Act of 1807 and subsequent abolition acts—that empowered the West Africa Squadron are
not in effect today. Those laws were tied to the legal framework of the British Empire and specific treaties, which have been superseded by modern international law.

However, the
principle of using naval force to combat slavery and piracy remains robustly supported by contemporary international law, allowing for similar, though more heavily regulated, actions in the present day.
1. Modern Equivalent Laws and Frameworks (2026)
While Britain cannot unilaterally impose its laws on foreign ships, the following frameworks allow the Royal Navy to act against modern slavery and piracy:
- UNCLOS (1982) Articles 99, 100, and 110:The United Nations Convention on the Law of the Sea (UNCLOS) serves as the "Constitution of the Oceans."
- Anti-Slavery (Art 99): Obliges every state to prevent and punish the transport of slaves in ships flying its flag. It declares that any slave taking refuge on board any ship, regardless of its flag, is free.
- Right of Visit (Art 110): Authorizes a warship to board a foreign ship on the high seas if there is reasonable ground to suspect it is engaged in the slave trade or piracy.
- Anti-Piracy (Art 100): Mandates that all states cooperate to repress piracy on the high seas.
- The UK Modern Slavery Act 2015: This law gives the UK jurisdiction over British vessels worldwide and allows for foreign travel restrictions and seizure of vessels involved in trafficking.
- 2000 Trafficking Protocol: Supplementing the UN Convention against Transnational Organized Crime, this allows states to take action against trafficking in persons, though it often requires flag-state consent for boarding.

2. Similarities and Differences in Enforcement
- Similar Actions: Royal Navy units can (and do) track, intercept, and board ships suspected of violating maritime law, particularly in operations targeting "shadow fleet" vessels, illegal trafficking, or piracy.
- Key Differences:
- Consensual Boarding: While the West Africa Squadron frequently boarded foreign ships without permission (due to treaties), modern naval actions generally require either UN authorization, flag-state consent, or clear evidence of piracy.
- Definition of Slavery: Modern slavery (trafficking, forced labor) differs from the "classic" slave trade, making it legally more complex to invoke the absolute right of visit solely based on "slave trading" suspicions, though it is still argued to be an evolutionary interpretation of UNCLOS.

3. Present-Day Legal Justification
Present-day "similar actions" are justified through
Universal Jurisdiction for piracy and, arguably, for human trafficking. The international community largely recognizes trafficking as a modern form of slavery that undermines fundamental human rights, thus authorizing warships to act against it under UNCLOS.

In essence, while the specific 19th-century
British statutes are gone, they were replaced by
global maritime laws that mirror the original intent: suppressing slavery and piracy on the high seas.
