delivered the opinion of the Court.
This is a suit to mature a workmen’s compensation award under Article 8307, Sec. 5a, Vernon’s Annotated Texas Civil Statutes, which provides that when the Industrial Accident Board enters an award requiring the insurance carrier to make weekly or monthly payments to an injured employee and the carrier thereafter fails or refuses, “without justifiable cause” to continue to make such payments promptly, the injured employee may bring suit to mature the award; that is, collect the full amount thereof, plus attorney’s fees and recover a twelve percent penalty.
Judgment in the district court was for the injured employee and such action was affirmed by the Court of Civil Appeals. *83See Travelers Insurance Company v. Jack Hill, Texas Civ. App., 344 S.W. 2d 208. Travelers, the insurance carrier as petitioner here, submits one point only, viz: the Court of Civil Appeals erred in holding that under the facts of this case a penalty could be imposed on the insurer even though the delay in making payment was desired and induced by respondent and his counsel. This point raises the question of whether or not the trial judge’s findings of fact support his conclusion of law.
From the findings of fact and the undisputed evidence, it appears that Jack Hill was accidently injured while working for the Sebastial Corporation. Pending action by the Industrial Accident Board, the insurance carrier paid Hill compensation for 29 weeks at the rate of $35.00 per week. On February 6, 1959, the Board made its final award whereby the carrier was ordered to pay to Hill certain weekly sums for a period of total disability followed by further sums payable weekly for permanent partial disability. On February 10 Hill filed with the Industrial Accident Board his notice of intention to appeal from the Board’s award. However, he did not perfect the appeal with the result that the Board’s award became final on March 2. Article 8307, Sec. 5, Vernon’s Annotated Texas Civil Statutes. Seventeen days later, on March 19, this suit was filed.
Travelers made no attempt to ascertain from Hill or his attorney whether or not a suit had been filed in the district court. Had it done so at any time after March 2 it would have ascertained that Hill was going to abide by the Board’s award. Based upon these facts, the court concluded that the period of seventeen days’ delay (from March 2 to March 19) was without justifiable cause and rendered judgment maturing the award with penalty and attorney’s fees. As above indicated, the Court of Civil Appeals affirmed.
The case of Minor v. London Guarantee & Accident Co., Limited, Texas Com. App., 280 S.W. 163, (holdings approved by the Supreme Court), is authority for the proposition that when an award is made by the Industrial Accident Board, and no appeal is taken therefrom, and the carrier failed to make payments promptly in accordance with the award, the claimant may mature the award under the provisions of Article 8307, Sec. 5a. We are not disposed to depart from that holding. As pointed out by the Court of Civil Appeals, the later holding of this Court in Maryland Casualty Co. v. Lewis, 151 Texas 480, 252 S.W. 2d 155, in no way militates against the doctrine stated in the Minor case. See also Dixon v. United States Fidelity & *84Guaranty Co., Texas Civ. App., 293 S.W. 291, wr. dism., and Texas Employers’ Ins. Ass’n. v. Harrington, Texas Civ. App., 61 S.W. 2d 167, no writ history.
We accordingly reach the question as to the legal effect of respondent’s giving notice of appeal from the Board’s award, but not perfecting such appeal and then failing to notify petitioner of such action, or demand payment of the award. In our opinion the rule is that when notice of appeal has been given and not perfected, the award may be matured whenever it is made to appear that the carrier knew or should have known, by the exercise of reasonable diligence, that the award of the Board had become final and payable.
In this case it may be assumed that the carrier had no actual knowledge that the award of the Board had become final. The trial court however made numerous findings to the effect that it should have known that the award was final and hence due and payable prior to March 19, when the suit to mature the award was filed. There is evidence supporting these findings. There is also evidence to support the trial court’s finding that the delay in payment of the award was without justifiable cause. The fact that the respondent gave notice of appeal from the Board’s award may work some change in the factual pattern disclosed in Minor v. London Guarantee & Accident Company, supra, in that the carrier may not have been chargeable with notice of the finality of the award immediately upon the expiration of the statutory twenty-day period for perfecting an appeal by filing suit in the district court. But here, as above pointed out, the last date for filing suit was March 2, yet the petitioner, although it had not been served with citation in a district court suit, waited seventeen days from March 2 until March 19, the date the maturity suit was filed, taking no action whatsoever. The trial court could well conclude that this delay in making proper inquiry as to the status of the award was without justifiable cause. It was said in the Minor case that “mere neglect to pay either the amount due under the order of the Board, or the weekly payments as they became due, does not show justifiable cause for defeating the beneficiary’s right to mature the entire claim, nor does it show justifiable cause to avoid payment of either of the 12 percent damages or reasonable attorney’s fee.”
Petitioner contends that respondent’s action in giving notice of his intention not to abide by the decision of the Board and then failing to file suit in the district court constitutes a form of entrapment. It points to evidence that respondent and his *85attorney were both hopeful that petitioner would overlook the fact that no appeal had been perfected and thus give respondent grounds for maturing the award. The trial judge found that when respondent filed his notice of intention of appeal it was not done with any intent on the part of respondent or respondent’s attorney to mislead the petitioner, but the notice of an intention to appeal was filed with the Board in good faith. The fact that when respondent subsequently decided not to perfect his appeal he entertained hopes that the insurance carrier would fail to resume weekly payments in accordance with the award and thus allow him to file a suit to mature the award cannot make the case one of entrapment or bad faith, as a matter of law, and thus permit this Court to disregard the trial judge’s findings as having no factual basis.
Further, we cannot say that respondent was required to demand payment of the Board’s award or notify the petitioner of his decision to abandon his proposed appeal and abide by the award. This for the reason that the statute nowhere required such demand or notice. Under certain circumstances some delay in payment may be permissible. The statute does not make a demand for payment necessary to render the claim due and payable. This Court, in discussing Secs. 5, 5a of Article 8307, Vernon’s Annotated Texas Civil Statutes, providing that in the event of no suit being filed to set aside an award against the compensation carrier, held in the case of Maryland Casualty Co. v. Lewis, supra, “it shall at once comply.” “ * * * The phrase at once has often been distinguished from other words or phrases importing immediate or instantaneous action, and in doing so the ‘courts have declared without qualification that it signified in a reasonable time.’ 7 C.J.S., at p. 160. And see 4 Words and Phrases, p. 682 et seq. * * *” There is evidence that supports the trial court’s judgment herein. If such demand under certain circumstances should be required, that is a matter for the legislative branch of the government.
The judgments of the district court and the Court of Civil Appeals are affirmed.
