Reversal is required; Samsung’s reports are exempt from PIA disclosure. ....................................................................................... 10

Samsung’s reports are confidential audit reports. ............... 13

Samsung’s investigation was “voluntary”

under the plain text of the Audit Privilege Act................................................................................. 14

Texas Water Code § 26.039 and TCEQ’s implementing rules confirm Samsung’s extended environmental investigation was voluntary. ..................................................................... 16

iii

The Attorney General’s interpretation fails. ............... 20

Samsung did not expressly waive its privilege; its reports are exempt from PIA disclosure. .............................. 25

Any “waiver” under the Audit Privilege Act must be “express.” ........................................................ 25

Regardless, Samsung disclosed its reports to TCEQ under a claim of confidentiality. ....................... 29

The Attorney General’s extra-textual interpretation fails. ...................................................... 30

a. Public knowledge of the discharge does not waive Samsung’s audit report confidentiality. .................................................... 30

b. The Audit Privilege Act does not impose a deadline to assert confidentiality. ...................... 31

c. TCEQ’s policy of not accepting “confidential” material is beside the point. ........ 32

Public policy weighs in favor of maintaining Samsung’s privilege, not PIA disclosure. ......................................................... 34
