No, I think they are lying when they say the ACLU is suing to "prevent the public from receiving public records from the Washington State Department of Corrections on the number of inmates in state custody who identify as transgender and the number of male inmates who are housed in women’s facilities" because there are no such records and they are actually suing to prevent the release of people's identities. They are also lying by omission and competently misrepresenting the case by not mentioning what other kind of information was requested and how the government intends to respond to the request for the statistics it doesn't possess.
How about a more charitable interpretation, rather than accusing people of lying: ACLU's position is that these shouldn't be public records, WoLF's is that the government should release whatever public records are required to fulfil the request.
