A judge has ruled against Oracle in its appeal of how the Pentagon handled its JEDI cloud contract.

Microsoft made headlines when it won the Joint Enterprise Defense Infrastructure (JEDI) Pentagon contract, worth some $10 billion. The win was seen as a major coup for the company as it continues to challenge Amazon’s dominance in the cloud market. Amazon immediately challenged the results in a case that has yet to be decided.

In a less publicized case, however, Oracle also challenged the Pentagon’s handling of the contract. According to Bloomberg, Oracle claimed the contract requirements unfairly favored Amazon and Microsoft, the two companies that emerged as early leading candidates.

Ultimately, the three-judge panel ruled that “notwithstanding the extensive array of claims raised by Oracle, we find no reversible error.”

The decision is a win for Microsoft, and could lend weight to the other case involving Amazon’s appeal.
