Jurisdiction of this court to consider this petition for a writ of review was questioned initially on the ground that petitioner is not a resident of this appellate district within the meaning of section 5950 of the Labor Code. Nevertheless, petitioner maintains that section 5950 of the Labor Code has never been enforced because petitioner consistently has been permitted to file in districts other than that of its residence; 1 that section 5950 of the Labor Code goes to the question of venue and not jurisdiction; that many factors are related to the Fourth District so that, in fairness to all concerned, the matter should be heard by this court. Specifically, the employer, the injured employee, and *672 the local office of petitioner are all located within this district. Moreover, the injury which gave rise to the claim and the original proceedings for disposition of the applicant’s claim occurred within this district. Such a combination of factors is sufficient to confer jurisdiction and venue in this tribunal.
The employee sustained an injury on the employer’s ranch near the City of Ontario in San Bernardino County. The ranch is maintained for the training of race horses and for developing potential jockeys. The employee, a 16-year-old youngster, lived in a dormitory or bunkhouse on the ranch, was paid a salary to aid in the care and training of the horses, and had ambitions of eventually becoming a thoroughbred pilot. While in the bunkhouse on Sunday, December 6, 1964, the emрloyee engaged in some youthful “fooling around” with other trainees of the same approximate age, and during the course of the “horseplay” threw a glass of Kool-Aid in the face of one of his fellow trainees. The coworker chased the claimant around the bunkhouse and caught and pushed him through a glass door, as a consequence of which the young man suffered lacerations of the arms and hands.
On August 31, 1965, the employee filed an application with the Industrial Accident Commission (predecessor of respondent Workmen’s Compensation Appeals Board). The referee, on December 14, 1965, filed findings and award determining the injury was not compensable on the ground the. injury did not occur in the course of employment. Applicant then petitioned for reconsideration on January 3, 1966. By a report filed February 18,1966, the identical referee recommended the petition be denied. Simultaneously on said date, some 67 days after the date of the оriginal order denying recovery, the respondent-board filed a notice of intention to reopen the ease pursuant to section 5803 of the Labor Code. The initial issue to be determined is whether the board exceeded its jurisdiction under section 5900, subdivision (b) of the Labor Code by reopening the case after the 60-day time limit prescribed therein had expired.
The “Opinion on Notice of Intention to Reopen” provides as follows:
“Appellant has petitioned from the Findings and Awаrd and Order filed December 14, 1965, intending (sic, contending) in effect that the trial referee erred in finding that he did not sustain an injury arising out of and occurring during the course of his employment. Applicant requested a tran *673 script in connection with his petition. Apparently the matter was held pending the preparation of the transcript so that it was not presented to the Board for consideration until jurisdiction was lost either to act upon applicant’s petition or for the Board to act оn its own motion. Therefore it seems just and proper that the matter be reopened on the Board’s own motion. If and when the matter is reopened consideration will be given to applicant’s petition and also to his request for oral argument.
‘ ‘ For the foregoing reasons:
“It Is Ordered that Case No. ... be reopened on the Board’s own motion pursuant to the provisions of Labor Code, Section 5803 unless good cause to the contrary has been shown in writing within ten (10) days from the service of this notice.”
On March 28, 1966, cоunsel for the parties stipulated the board might reopen the case and consider applicant’s contentions as set forth in his petition for reconsideration.
Reconsideration is, in effect, an appeal to the board from the trial referee’s determination, and the reconsideration remedy is entirely distinct from the procedure for reopening a cause. Any person aggrieved, directly or indirectly, by any final order, decision, or award filed by a referee may petition for reconsideration (Lab. Code, § 5900, subd. (a)), or the commission may, on its own motion, grant reconsideration at any time within 60 days after the filing of such order, decision, or award of a referee (Lab. Code, § 5900, subd. (b)).
When reconsideration is granted under section 5900, subdivision (b) of the Labor Code, there is no requirement of a showing of “good cause” as the basis for reconsideration.
(Argonaut Ins. Exchange

Industrial Acc. Com.,
The board is not required to take further evidence, but may redetermine the case on the existing record pursuant to its statutory powers.
(Argonaut Ins. Exchange
v.
Industrial Acc. Com., supra,
Where an employee’s petition for reconsideration is denied by operation of law, it has been held further action of the board affecting a previous award exceeds its powers.
(Llewellyn Iron Works
v.
Industrial Acc. Corn.,
On the other hand, the board has continuing jurisdiction to reopen for five years from the date of injury. The board may reopen under section 5410 of the Labor Code оn the ground of new and further disability occurring within the five-year period, even though the board’s action is effected after the lapse of the five-year period, provided the application is filed within the five-year period.
(Westvaco etc. Corp.
v.
Industrial Acc. Com.,
The board also has continuing jurisdiction for five years to reopen under sections 5803 and 5804 of the Labor Code, to alter, amend, rescind, or change an order in any way if
good cause
appears for reopening.
(DeCelle
v.
City of Alameda,
Before the expiration of the five-year period, the board can act undеr section 5803 or 5804 of the Labor Code, or can act under section 5410. After the expiration of the five-year period, the board has no power to act under section 5803 or 5804, except where a petition to rescind, alter, or amend is filed by a party in interest, within the five-year period. Absent such a petition, and after the expiration of the five-year period, the board can only act under section 5410. (See
Westvaco etc. Corp.
v.
Industrial Acc. Com., supra,
*675 In this case, the board’s good cause for reopening under sections 5803 and 5804 of the Labor Code, no new and further disability appearing within the meaning of section 5410 of the Labor Code, was the inequity in allowing an unintended lapse of time in examining the employee’s petition for reconsideration under section 5900 to be deemed a denial of the petition for reconsideration pursuant to section 5909 of the Labor Code.
A similar issue was determined in a case involving
reconsideration
in
United States Pipe & Foundry Co.
v.
Industrial Acc. Com.,
Quoting further from the opinion of the court:
“The commission seeks to sustain its order on a second ground; it urges that instead of treating its ruling as a decision after reconsideration, we should regard it as a decision after reopening, pursuant to Labor Code section 5803. As we have above indicated, however, we do not believe this order, subject to error and infirmity, can be so lightly converted into a different, if valid, one. Í <
“. . . The content of a рrocedure should not be subject to alteration by title. . . .
“. . . The process of the reopening of the case is not identical with the process of reconsideration, and this difference introduces in the instant case problems of due process. Section 5803 of the Labor Code sets out the procedure of reopening: ‘At any time, upon notice and after an opportunity to be heard is given to the parties in interest, the commission may rescind, alter, or amend any such order, decision, or award, good cause appearing therefor.’ [Emphasis by the court.] The interested party must be given notice and opportunity to be heard, and one of the issues upon which he is to be heard is whether or not ‘good cause’ justifies the reopening. . . .
*676 "The interested party here, the petitioner, did not receive notice that the hearing pertained to the issue of the reopening of the ease under Labor Code section 5803. The commission does not contend that petitioner Imew that the commission purported to act pursuant to that section. . . . The commission did not give petitioner adequate notice of any purported procedure under section 5803.
"... On the other hand, we do not mean to suggest that the commission may not, pursuant to the provisions of Labor Code section 5803, upon its finding of good cause, reopen this case. ...” (Emphasis added.)
In this case the board issued and served all parties with written notice of intention to rеopen pursuant to section 5803 of the Labor Code, giving its reasons therefor, and granting the parties 10 days to file objections to reopening. The parties not only failed to object, but executed a written stipulation to the effect that the board should reopen under section 5803 of the Labor Code and consider the contentions of the applicant’s petition. The board’s misleading wording in its final disposition of the applicant’s claim, "Opinion and Order (Granting Reconsiderаtion on the Appeals Board’s own motion pursuant to Labor Code 5900(b)) and Decision (After Reconsideration), ” is not dispositive of the true nature of the order in view of the good cause which supported reopening under section 5803 of the Labor Code, particularly in the absence of the due process objections presented in
United States Pipe & Foundry Co.
v.
Industrial Acc. Com., supra,
The second issue presented on review is whether the board’s finding is valid to the effect the claimant sustained an injury which arose out of and in the scope of his employment.
Under section 3600 of the Labor Code, in order to be compensable, an injury must both arise out of, and be in the course of employment. Generally, the phrase "in the course of employment” refers to the time and place of the injury.
(State Comp. Ins. Fund
v.
Industrial Acc. Com.,
Both parties concede that the resolution of this question depends on whether the “bunkhouse rule,” relating to whether the injury was one “in the course of employment” supersedes the “horseplay rule,” relating to whether the injury was one 11 arising out of the employment. ’ ’
The bunkhouse rule is merely an extension of the general rule that where an employee is injured on his еmployer’s premises as contemplated by his contract of employment, he is entitled to compensation for injuries received during reasonable and anticipatable use of the premises.
(Rosen
v.
Industrial Acc. Com.,
The underlying rationale of the bunkhouse rule is best illustrated by reference to the leading California eases in which the rule has been developed and applied. (See

Petitioner correctly notes that this injury occurred on a Sunday afternoon, a nonworking day, and that neither claimant nor his fellow-employees were obliged to remain on the premises on an off-duty day. Nevertheless, an injury is compensable if received while the employee is engaged in those normal activitiеs which his contract of employment expressly or impliedly authorizes him to do.
(Employers’ etc. Corp.
v.
Industrial Acc. Com., supra,
The record indicates that the boys were engaged in their customary Sunday recreation at the time of the injury. Whether the employee was acting reasonably at the time of his injury, as the board must have found, is essentially a

question of fact which it is beyond the power of this court to disturb. When a finding of the board is attacked on the ground that there is not any substantial evidence to sustain it, the power of an appellate court
begins
and

with a determination as to whether there is any substantial evidence, contradicted or uncontradicted, which will support the finding.

supra,
Another major exception to eases denying recovery under the horseplay rule is the circumstance in which the employer has actual or constructive knowledge of customary or habitual horseplay among his employees. Under such conditions, the employer’s knowledge of the horseplay, without voicing objection, makes it a hazard closely associated with the work. Consequently, an injury incurred under such circumstances arises out of the employment and is compensable. In
McNicols
case (1931)
Apparently, no California case authority exists which expressly recognizes and applies the foregoing exception to the horseplay rule. However, there are a few California decisions which appear to sanction the validity of the exception but find it inapplicable to the facts of the particular case presented. In
Great Western Power Co.
v.
Industrial Acc. Com., supra,
It is this exception to the horseplay rule which finds both recognition and application in the instant ease. Whether the employee’s horseplay was customary and known by the employer to be so without objection on the employer’s part, as the board must have found is essentially a question of fact which it is beyond the power оf this court to set aside. When a finding of the board is attacked on the ground that there is no substantial evidence to sustain it, the power of an appellate court
begins
and
ends
with a determination as to whether there is any substantial evidence, contradicted or uncontradicted, which will support the finding.
(Douglas Aircraft, Inc.
v.
Industrial Acc. Com., supra,
In recognizing and applying what might be described as the “condonation” exception to the horseplay rule, we make no distinction between the participant and the nonparticipant. In the case at bench, it seems clear that the applicant was a participant in, the horseplay which resulted in his injury. The applicant’s participation in the horseplay is not decisive if the employer condones the horseplay in the first instance.
We do not hold, as the respondent would apparently have us hold, that the bunkhouse rule supersedes the horseplay rule in all circumstances. We do hold that the bunkhouse rule supersedes the horseplay rule under the circumstances presented in this ease where horseplay is closely connected with the injured party’s presence in the bunkhouse, such horseplay is known to and apparently condoned by the employer, and the injured party’s presence in the bunkhouse is closely connected with his employment. These circumstances fall within the underlying philosophy of the Workmen’s Compensation Act that work-connected injuries are compensable. Under these facts, the injury has “arisen out of and in the course of employment” within the meaning of section 3600 of the Labor Code. (See Riesenfeld, Contemporary Trends in *682 Compensation for Industrial Accident, 42 Cal.L.Rev. 531, 546.)
The final issue requiring disposition is whether the applicant was the aggressor in an altercation within the meaning of subdivision (g) of section 3600 of the Labor Code so as to bar his claim for benefits.
In 1952 the California Supreme Court held that an employee who engaged in a fight with his foreman, in which the employee was the instigator, may not be stepping aside from his employmеnt if the fight was closely connected to the employment.
(State Comp. Ins. Fund
v.
Industrial Acc. Com., supra,
In 1961 the Legislature amended section 3600 of the Labor Code, apparently to nullify the aforesaid decision in
State Comp. Ins. Fund
v.
Industrial Acc. Com., supra,
Section 3600 of the Labor Code, as amended, provides in part: “Liability for the compensation provided by this division, in lieu of any other liability whatsoever to any person except as provided in Section 3706, shall, without regard to negligence, exist against an employer for any injury sustained by his employees arising out of and in the course of the employment and for the death of any employee if the injury proximately causes death, in those cases where the following conditions of compensation concur: (g) where the injury does not arise out of an altercation in which the injured employee is the initial physical aggressor. ’ ’
Horseplay is distinguishable from “altercation.” “Altercation” indicates willingness to inflict, or the actual infliction of, bodily harm.
(Rosenthal
v.
Voy Wong,
Although the two elements “arising out of” and “in the course of employment” must coexist concurrently to sustain an award, these elements are often so intertwined that no valid distinction can be made.

The court in
Madin
v.
Industrial Acc. Com., supra,
In the case at bench it cannot be said that the employee's injury was so remote from the employment as not to be an incident of that employment. In point of actual fact, it can be fairly stated the injury was directly related to the employment.
The award of the Workmen’s Compensation Appeals Board is affirmed. Writ denied.
