Leahy Law provisions are sometimes confused with human rights conditionality that applies to overall Foreign Operations aid packages to a specific country, such as Colombia, Mexico, or Guatemala. Leahy Law applies only to assistance to specific units, and does not necessarily affect the level of assistance to a country, even when implemented. Human rights conditionality, on the other hand, typically requires a percentage of assistance to a country to be withheld until the Department of State certifies progress on certain human rights conditions.
