A care home tried to get an injunction to stop publication of a report rating it "inadequate", it has been revealed.
The Care Quality Commission (CQC) found residents at Acomb Court in Hexham, Northumberland, were not always given respect, privacy and dignity.
In its report residents said some staff were "rough and rushed and not very sympathetic".
The home said inspectors "got it wrong". The CQC said it was satisfied its findings were correct.
Acomb Court caters for people who need nursing, residential or dementia care.
Inspectors found staff did not always seem caring and compassionate, although most residents reported feeling safe and comfortable.
They found some residents were unhappy in the "glum environment".
Acomb Court owner, Helen McArdle Care, sought an injunction at the High Court to prevent the report being made public, but it was refused.
The home then said it would appeal against the report's rating.
Some areas had been addressed but the "inspection process fell short in terms of objectivity and evidence-gathering", it said.
Debbie Westhead, CQC regional deputy chief inspector for adult social care, said the regulator had a "duty to ensure the public have clear and accurate information about the performance of their care services".
The CQC applied "strong quality control and assurance processes" to its reports and ratings and let care providers "share their views on the factual accuracy of our inspection reports before they are published", she said.
