The threat of Spanish invasion in support of Mary was removed by the fact that England was now at war with Spain. So putting Mary on trial for treason would make no difference.

Ordering Mary's trial for treason was no easier for Elizabeth than it had been in 1572. She was Elizabeth's cousin, Queen of Scotland and legitimate heir to the English throne.

By ignoring evidence against Mary and doing nothing, Elizabeth would continue to keep her options open.

Elizabeth could no longer afford to do nothing. With definite proof of Mary's involvement in the Babington Plot, Elizabeth would face overwhelming pressure from her Council to place Mary on trial.
