Thеse consolidated appeals arose out of two lawsuits brought against Detroit Edison Company (hereinafter Edison) for negligence in failing to provide two employeеs of Reliance Truck Company (hereafter Reliance) with a safe placе to work._
*282 In the fall of 1976, Edison was allowed to file third-party complaints against Reliance. Reliance subsequently filed motions for summary judgment on each third-party complaint. The motions were based on the fact that both Reliance and Edison were insured by Hartford Acсident and Indemnity Company. Reliance argued that since it is impossible to sue oneself, thе complaints should be dismissed. Edison believed that Reliance’s interpretation of the insurаnce policy was correct and did not oppose the motions. The motions for summary judgment were granted on March 22, 1978.
On February 2, 1979, Edison filed motions to set aside the orders dismissing the third-party complaints. Edison alleged that since the orders were entered, it had becоme aware of an exception in its insurance policy which would allow suit against Reliance. Edison argued that the lower court should set aside the summary judgments based on GCR 1963, 528.3. The lоwer court disagreed and denied Edison’s motions on March 7, 1979.
GCR 1963, 528.3 provides relief from a final judgmеnt or order under certain limited circumstances. Two of these reasons have been alleged by Edison here:
"(1) mistake, inadvertence, surprise, or excusable neglect; [and] * * *
"(6) any other reason justifying relief from the operation of the judgment.”
The lower court found no reason to set aside the summary judgments. This was a discretionary decision, one which will not be disturbed on appeal absent a clear showing of an abuse of discretion. Sеe
O’Neill v O’Neill,
*283 Edison first claims that it made a mistake by not opposing the motions for summary judgment. We do nоt believe that GCR 1963, 528.3(1) was designed to relieve counsel of ill-advised or careless decisions. See Federal’s Inc v Edmonton Investment Co, 555 F2d 577 (CA 6, 1977), Hoffman v Celebrezze, 405 F2d 833 (CA 8, 1969). Its application should be limited to extraordinary circumstances where the failure to set aside the court’s final determination will result in substantial injustice.
In
Kibby v Rhoads,
We find Edison’s actions to be equally indefensible. Edison consciously chose not to answеr the summary judgment motions because it believed Reliance’s insurance contract covered the accidents. With diligence, Edison easily could have read the contract and discovered that the accidents were not covered; thus, Reliance сould have been sued. We will not equate this lack of due diligence with the mistake or exсusable neglect *284 required under the rule for setting aside a judgment.
Edison also alleges that relief should be granted under GCR 1963, 528.3(6), for "any other reason justifying relief from the operation of the judgment”. As stated in
Kaleal v Kaleal,
Edison’s claim fails on all three counts. First, Edison has failed to allege any reason for setting aside the judgment beyond the mistake or neglect which is encompassed in subrule (1). Furthermore, as the lower court recognized, Reliance has now been prejudiсed by the ten-month lapse since the summary judgment was entered. For example, during the ten mоnths, Reliance personnel freely gave information to Edison, thinking that Reliance was nо longer liable. Finally, we do not believe that the instant facts reflect the type of extraordinary circumstances which would justify relief. We must conclude, therefore, that the trial judge did not abuse his discretion in denying Edison’s motions to set aside the judgment.
