"admitted allegation"?

[Joel S. Berson]

Cardinal Justin Rigali of Philadelphia is quoted as having said, in
response to the grand jury report, that  ' there were no priests in
active ministry "who have an admitted or established allegation of
sexual abuse of a minor against them." '

NYTimes, March 9, "Philadelphia Cardinal Suspending 21 Priests", by
Catharaine Q. Seelye.

How does an "allegation" become "admitted"?  Or "established"?

Joel
