U.S. District Judge Amit Mehta has been scrutinized as the Justice Department's antitrust case against Alphabet Inc's (GOOG  ) (GOOGL  ) Google unfolds, with significant portions conducted behind closed doors.

Critics have accused him of being too accommodating to Google and other involved parties, including Apple Inc (AAPL  ), in their requests to seal the courtroom.

During recent proceedings, which included the questioning of top Apple executives, Mehta defended his stance, explaining that he relied on government lawyers to counter Google and other tech companies' repeated efforts to maintain confidentiality.

The DOJ asserts that Google used agreements with Apple and other phone manufacturers to stifle competition among search engines, WSJ noted.

However, Google has redacted much information regarding the contracts in question, repeatedly seeking to seal the courtroom.

The ongoing nonjury trial, which began on September 12, provides insights into how Google solidified its position as a major internet gateway, a position the Justice Department claims resulted from illegal, restrictive agreements.

Yet, the public cannot listen to the 10-week trial, potentially holding the key to Google's future business practices or a company breakup.

Although some testimony during Tuesday and Wednesday was open to the public, it's unclear whether Mehta's approach to sealing has shifted. U.S. law allows companies to petition for sealing to protect sensitive business information, but judges must weigh this interest against the public's right to access court proceedings.

Price Action: GOOG shares are up 0.39% at $131.98 during the premarket session on the last check Thursday.
