Which Ethical Standard Should Apply When the Host Country Allows Something the Researcher’s Home Institution Does Not?

What If the Research Is Allowed There but Not at Home?

A researcher’s institution prohibits a particular recruitment practice, consent procedure, level of participant compensation, or research procedure. The same practice is permitted in the country where the research will take place. Can the researcher simply follow the host country’s standard?

This is one of the harder problems in international research ethics because legal permission and ethical acceptability are not identical. Respect for host-country authority matters, but conducting research abroad should not become a way to escape protections that would constrain the same researcher at home.

Host-Country Permission Does Not Cancel Home-Institution Obligations

Why “It Is Legal There” Does Not Settle the Ethical Question

Permission and Ethical Acceptability Are Different Questions

A host country can legally permit an activity without requiring a researcher’s home university to permit its own researchers to undertake it. Institutions, funders, professional bodies, and research ethics committees may impose obligations beyond the minimum required by local law.

Before deciding what standard applies, identify the source of the restriction. Is the home-country rule a law, an institutional policy, a condition imposed by the approving ethics committee, a funder requirement, or an ethical recommendation? The answer affects what options are available.

Those propositions are not interchangeable. “The host country allows it” answers only part of the governance question.

The Declaration of Helsinki Rejects Reducing Participant Protections

For medical research involving human participants, the 2024 World Medical Association Declaration of Helsinki provides a clear principle. Researchers must consider ethical, legal, and regulatory standards both where research originates and where it is performed, together with applicable international standards. It states that no such requirement should reduce or eliminate the participant protections established by the Declaration.

This does not mean that every home-country procedure must be exported unchanged. It means that crossing a border should not become a mechanism for lowering protections that international ethical standards regard as necessary.

Moving Research to a More Permissive Setting Can Become Ethics Dumping

A particularly serious problem arises when researchers deliberately conduct an activity in a setting with weaker regulation or fewer resources because it would face ethical barriers at home. This practice is commonly described as ethics dumping.

The TRUST Code for Equitable Research Partnerships was developed specifically to counter ethics dumping and double standards in international research, particularly where substantial inequalities of power, resources, and knowledge exist between partners.

Location should therefore have an ethically relevant reason. A host country should not be attractive merely because participants there receive fewer protections or because regulatory scrutiny is easier to satisfy.

But the Home Standard Is Not Automatically the Universal Standard

The opposite mistake is to assume that whatever the home institution requires must represent the ethically superior practice everywhere. Some requirements reflect a particular legal system, administrative convention, or cultural understanding rather than a universally preferable method of protecting participants.

For example, a home institution might ordinarily expect signed documentation of consent. In a setting where possession of a signed document could expose participants to stigma, surveillance, or legal danger, insisting on that procedure could actually increase risk. A context-sensitive alternative may better serve the ethical purpose of informed consent, provided the responsible ethics committees approve it.

International research therefore requires more careful reasoning than exporting the strictest-looking procedure.

Ask What Protection the Home Requirement Is Trying to Provide

When a host-country procedure differs from the home requirement, identify the ethical purpose behind the home restriction. Is it intended to protect voluntariness, privacy, safety, scientific validity, fair participant selection, confidentiality, or another legitimate interest?

Then ask whether the host-country procedure protects that interest in another defensible way. If it does, there may be grounds for a formally approved site-specific adaptation. If it does not, the difference may amount to a genuine reduction in protection.

Local Ethics Review Is Essential to Understanding Context

A home committee may recognize a participant protection without understanding how its usual implementation functions locally. Conversely, a host-country committee may understand the local environment but not know all the obligations binding the external researcher.

This is one reason the Declaration of Helsinki requires ethics committees reviewing international medical research to have familiarity with local circumstances and requires collaborative international research to receive approval in both sponsoring and host countries.

If those bodies impose different requirements, researchers should use the procedures for reconciling ethics requirements across countries rather than privately choosing one standard.

Human Rights Set Limits on Appeals to Local Practice

Respect for cultural and national diversity is ethically important, but it is not unlimited. UNESCO’s Universal Declaration on Bioethics and Human Rights recognizes cultural diversity and pluralism while grounding bioethical principles in human dignity, human rights, and fundamental freedoms.

This matters because “that is acceptable locally” cannot by itself justify coercion, discrimination, avoidable exploitation, or serious reductions in participant protection. Cultural responsiveness and fundamental protections need to be considered together.

Sometimes the Study Must Change or Stop

There may be no legitimate compromise. If the home institution retains a binding prohibition, the researcher cannot simply bypass it by conducting the activity abroad. If a necessary protection cannot be maintained in the host setting, the protocol may need modification.

In some cases, the ethically defensible conclusion is that the activity should not be conducted as designed. International collaboration creates opportunities for research, not an exemption from inconvenient obligations.

When a More Permissive Local Rule Is Not Enough

Common Mistakes When Host and Home Standards Differ

Test the Difference Before Treating It as Permission

When the host country permits something your institution prohibits, do not begin by asking which rule is easier. Identify why the standards differ and which obligations remain binding on the project.

This approach avoids both extremes. Researchers should not exploit permissive environments, but neither should they assume that their own country's ethical assumptions can simply be transplanted into another cultural setting.
