Are BIR rulings confidential?

A few weeks ago, I attended a meeting where it was discussed that Bureau of Internal Revenue (BIR) rulings are no longer published.
Suddenly losing my appetite, I decided to forego dessert and coffee and instead, concentrated on listening to the discussion. The speaker said that BIR rulings must be kept private because they contain confidential information of the taxpayers which can violate the taxpayer’s right to confidentiality. In some cases, it was noted that even bank account details are included in the rulings necessitating the need to keep them private.
