Once the investigations and formal processes were completed, an official statement from the university would be released. Following the plagiarism allegations, Verijenko resigned from the university via email from Australia, where he is on a sabbatical.
Shaik has also since announced that he will be emigrating to Australia and cited the reports about his doctoral thesis as being the final straw. He challenged the university to prove plagiarism in his thesis.
Of the last sentence, one would hope that one can prove unattributed copying, one way or another, without difficulty.

The Des Moines Register noted:
It's not always dishonesty that leads students to fail to properly credit sources. Aside from wholesale copying because they're rushed, lazy or think an assignment is stupid, they might not fully understand what plagiarism is. Even educators sometimes disagree, such as: When is a fact such common knowledge no attribution is needed?
Does this concern apply to some of the Ohio University theses?
IPBiz notes that there are other issues. For example, can there be unintentional plagiarism, wherein a later author "borrows" from an earlier author on a matter that is not common knowledge but wherein the later author "forgot about" the earlier author? Also, is there an "independent creation" defense to plagiarism, wherein the later author simply did not know about the earlier author? In the examples involving students writing on specific assigned topics, there are only so many ways to address points and a student might write in a previously expressed way, without having seen the previous work.
The Cha matter reflects still other issues. For example, what is the responsibility of later co-authors for the plagiarism of one co-author?
