complementarity principle


Also found in: Dictionary, Thesaurus, Medical.

complementarity principle,

physical principle enunciated by Niels Bohr in 1928 stating that certain physical concepts are complementary. If two concepts are complementary, an experiment that clearly illustrates one concept will obscure the other complementary one. For example, an experiment that illustrates the particle properties of light will not show any of the wave properties of light. This principle also implies that only certain kinds of information can be gained in a particular experiment. Some other information that is equally important cannot be measured simultaneously and is lost.

In particular, in a key filing before the ICC, the Kenyan government sought to establish the case against the suspects as inadmissible under the complementarity principle. (192) For example, in its filing, the Kenyan government cited judicial and constitutional reforms such as the drafting of a new constitution, which included strengthened trial rights and revamped national courts now able to try "crimes from the post-election violence, including the ICC cases ...," (193) Kenya also cited its efforts to investigate and prosecute a number of lower-level perpetrators in the post-election violence.
