Abstract: | SETI projects raise legal problems which neither national nor international laws tackle properly. The protection of experiments is necessary, and should be afforded at both national and international levels. Radio is particularly important. It would also be prudent to establish in proper legal form, and preferably by formal international agreement through an appropriate forum, key evidence of ETI should be dealt with, and, if necessary, responded to. Whether a similar step should be taken as to a reply is uncertain. |
