Does any university require reporting of misconduct at other universities? Some universities have ethics codes that require (whatever that might mean) members to report misconduct within the community.

Are there universities where such a requirement extends to reporting misconduct within the "larger academic community"?  For example, if someone at school X learned that someone at school Y had falsified laboratory data, the X person would be required to report the person at Y.  

The example of falsified data is imperfect as it may be covered under legal and contractual rubrics not local to a university, such as a government grant agency requiring recipients to report any known misuse of government funds.   A better example is plagiarism in student papers, that usually does not violate any legal codes (unless additional scholarship money is earned through the plagiarism), and is treated as a reportable crime only within universities' internal ethics codes.  The question is whether any of those codes purport to protect the integrity of other institutions.

I'm asking only about reporting of academic or institutional misconduct, especially the kind where the only effective means of reporting is to the other university.
in case of publications and falsified data you are first and
foremost responsible to report it to the publication. They need to
first approve or review the technicality of the matter which can
become material for the ethics committee.
The Honor Committees of universities keep a record of students and
faculties, and when students or professors apply to other
universities they are generally being asked about the previously
notable issues with ethics in the previous institution. Lying in
those form can by itself be lying to the second institution even if
the matter can not be investigated with the first institute. That
being said Honor committees in university X might have a threshold
and limit before noting an offense or violation on the record
subject to citations and referral for future. In some cases in
universities, some mandatory 6 session therapy is being recommended
as a way to remove an item from someones active record.Those
therapies are subect to confidentiality and therfore can not be
cited by university Y.
