No. In an ordinary two-innings match under the stated MCC framework, equal totals produce a tie only after every innings has been completed. Equal numbers while the final innings is still in progress are not, by themselves, a result.
When the equal totals become a tie
Hypothetical example: Team A scores 250 in its first innings and 150 in its second. Its aggregate is 250 + 150 = 400. Team B scores 200 in its first innings and 200 in its second. Its aggregate is 200 + 200 = 400.
If both sides’ innings are complete, the match ends with equal scores. Under MCC Law 16.5, that completed-match condition is a tie. The evidence needed is therefore twofold: the totals are equal, and all innings have finished.
Why the same numbers may not settle the match
Now use the same aggregate figures, but change the match state. Suppose Team A has completed both innings for 400, while Team B has reached 400 during its second innings and is still batting. The scoreboard numbers currently match, but Team B’s final innings has not ended.
That situation cannot yet be called a tie from the numbers alone. Team B might add runs, lose its remaining wickets, or reach another innings-ending event. The eventual result is not given by this example; the important limit is that a live final innings leaves the match unresolved for this question.
Tie is different from a draw
A tie requires completed innings and equal scores in this framework. A draw is different: it describes a match that has not been decided by the other stated result categories. Thus, “the totals are equal” does not automatically mean “the match is tied,” and “the match is drawn” does not mean both teams finished with equal totals.
This explanation is limited to the ordinary two-innings setup described here. Competition playing conditions may specify different result arrangements, including formats with other agreed conditions, so those cannot be inferred from this worked example.
