PerspectiveSome Synthetic Biology May Not be Covered by the Biological Weapons Convention

Published 18 May 2020

The study of viruses once challenged the world’s notion of what is “biological,” and for a time it was not clear whether viruses were regulated by the Biological Weapons Convention (BWC). Durward Johnson and James Kraska write that “SynBio and its convergence with emerging technologies may create weapons not currently banned by universal disarmament obligations or customary international law, and this legal gap raises the prospect of weaponization of nonbiological threat agents tailor-made to create targeted effects. These tactical biotechnological capabilities could have potentially strategic consequences and yet may fall outside the existing regime.”

The study of viruses once challenged the world’s notion of what is “biological,” and for a time it was not clear whether viruses were regulated by the Biological Weapons Convention (BWC). Durward Johnson and James Kraska write in Lawfarethat viruses, lying “at the edge of life,” likely were not banned as a biological weapon until they were defined as a biological agent in 1969, more than 40 years after the first multilateral treaty prohibited biological warfare.

Johnson and Kraska add:

Viruses infect their hosts by multiplying through living cells, many spreading disease from one person to another, like the current novel coronavirus causes COVID-19. while today viruses are considered to be an infectious biological agent and are categorically banned as a method of warfare, some types of synthetic biology (SynBio) may pose a similar dilemma and yet may not be covered by the same restrictions.

SynBio includes a host of technologies used to redesign organisms by engineering them to have new properties or abilities, or to use nonbiological materials that mimic biological effects, called biomimetics. While Article I of the BWC codifies the customary law prohibition against weaponizing biological material or pathogens, the agreement does not necessarily cover the development or employment of biomimetics, a dangerous subclass of SynBio. Such material may be weaponized into nonbiological agents that alter biological organisms, challenging the very definition of “biological material.” This scientific uncertainty has opened a lacunae in the law, and it is unclear whether the member states of the BWC can close it.

They conclude:

SynBio and its convergence with emerging technologies may create weapons not currently banned by universal disarmament obligations or customary international law, and this legal gap raises the prospect of weaponization of nonbiological threat agents tailor-made to create targeted effects. These tactical biotechnological capabilities could have potentially strategic consequences and yet may fall outside the existing regime.
